The short answer
Pro-fax SE012 is a LyondellBasell low melt flow, electrical grade polypropylene copolymer, not a homopolymer. LyondellBasell lists it for oil well logging cables, data cables and heavier wall insulation, processed by wire and cable extrusion or injection molding. Published melt flow rate is 1.5 g/10 min at 230°C / 2.16 kg (ISO 1133-1) and density is 0.90 g/cm³ (ISO 1183-1). The data sheet lists no nucleating or antistatic agent. LyondellBasell lists its availability as North America only, and it was not part of the Velogy rename in Europe. Grades to ask about are Pro-fax EP315J and Pro-fax SV258. They are not identical, so compare the data sheets and run a trial before switching.
Also written as: Profax SE012, Pro-Fax SE012, SE012. LyondellBasell’s product page lists no color or additive suffixes for this grade. Quote the full code from your drawing or bag label.

Grades to ask about instead of Pro-fax SE012
These grades have related published specs. None is a drop-in replacement: additive packages, copper stabilization, electrical values and approvals differ. Both are LyondellBasell grades; we did not find another producer’s published North American wire and cable PP copolymer at similar flow to list here. If your cable construction, drawing or customer approval names Pro-fax SE012, any change needs your approval and usually a trial.
| Grade | Producer | Melt flow | Density | Key property | How it compares |
|---|---|---|---|---|---|
| Pro-fax EP315J | LyondellBasell | 2.6 g/10 min (230°C / 446°F, 2.16 kg, ASTM D1238) | 0.90 g/cm³ (23°C, ASTM D1505) | Flexural modulus, 1% secant 1,030 MPa (150,000 psi) (ASTM D790); tensile stress at yield 22 MPa (3,200 psi) (ASTM D638); dielectric constant 2.25 and dissipation factor 0.0003 at 1 MHz (ASTM D150); oxidative induction time >20 min at 200°C (ASTM D3895) | Ask about. Also an electrical grade PP copolymer, used for primary insulation, with an additive package that LyondellBasell says helps prevent degradation from copper. LyondellBasell states it meets ASTM D 4101, Group 03, Class 4, Grade 8. It flows faster (2.6 vs. 1.5 g/10 min). Its published modulus is ASTM 1% secant while SE012’s is ISO 178, so the two stiffness numbers cannot be compared directly; compare at the same method. LyondellBasell lists wire and cable processing only, not injection molding. Quote this alternative › |
| Pro-fax SV258 | LyondellBasell | 1.2 g/10 min (230°C / 446°F, 2.16 kg, ASTM D1238) | 0.90 g/cm³ (23°C, ASTM D792) | Flexural modulus, 1% secant 1,240 MPa (180,000 psi) (ASTM D790, Procedure A); notched Izod 208 J/m (3.9 ft-lb/in) (ASTM D256, Method A); deflection temperature 82°C (180°F) at 0.45 MPa (66 psi), unannealed (ASTM D648) | Check. An impact copolymer at similar flow for extrusion, with very good cold temperature impact resistance. LyondellBasell does not describe it as an electrical grade or mention copper stabilization; it lists sheet, profile, blow molding, thermoforming and compounding. Treat it as a non-wire option and run your insulation and copper aging tests before use. See our Pro-fax SV258 page. Quote this alternative › |

Typical uses for Pro-fax SE012
LyondellBasell lists these uses:
- Oil well logging cables
- Data cables
- Heavier wall insulation
LyondellBasell says the resin is tailored for heavy and thin walled constructions and cites toughness, flex life, abrasion resistance, resistance to stress cracking, solvent and chemical resistance, good colorability and proven life in the presence of copper. For other wire and cable materials, see wire and cable compounds.
What to check before you switch
- Confirm the exact grade code on your approval or bag label. SE012 is a copolymer; do not swap in a homopolymer because the melt flow looks close.
- SE012’s data sheet uses ISO methods. EP315J and SV258 are published on ASTM methods, so notched Izod in kJ/m² (ISO 180) and J/m (ASTM D256) cannot be compared directly.
- Copper contact matters. LyondellBasell cites proven life in the presence of copper for SE012 and copper protection for EP315J; SV258 makes no such claim. Run your heat aging test on conductor before you release a change.
- SE012’s data sheet gives no dielectric values. If your cable spec has them, ask for test data or test the insulation yourself.
- LyondellBasell gives no mold shrinkage value and asks you to contact it for shrinkage recommendations. For insulation, see its guide on troubleshooting excessive shrinkback.
- If you color the insulation, check the masterbatch carrier and loading. LyondellBasell links a paper on carbon black masterbatches in wire and cable from the SE012 page.
- Run a trial lot and check concentricity, surface, shrinkback and electrical results before you switch production.

Buying Pro-fax SE012: price, lead time and lot size
- Lot size. From one gaylord to a railcar. See gaylord, LTL and truckload for typical weights per box.
- Where it ships from. We have access to 100+ partner warehouse locations. Material already in a partner warehouse usually moves sooner than a grade that has to come from the producer; your quote says which applies. Lead time is confirmed with your quote.
- Price. We do not publish prices because they move with feedstock, freight and order size. What moves your price most: lot size, color, ship-to region, and whether you need Pro-fax SE012 itself or can accept a matched alternative. See how resin is priced and the monthly market update.
- Paperwork. Supplier COA on every prime lot (what a COA shows). Ask for LyondellBasell’s Product Stewardship Bulletin if your cable needs regulatory documents. Payment terms are confirmed with your quote.
- Trying an alternative? Start with one gaylord as a trial lot, extruded and tested before you commit a full release. Samples (~50 lb) are available upon credit approval.
- If Pro-fax SE012 itself is not available. Some branded grades are sold only through the producer’s own channels or go on allocation. If we cannot source it, we tell you, then quote a matched alternative with a side-by-side comparison.
Send the grade code, your annual volume and ship-to location. A polymer chemist checks it before we quote. For several grades at once, use the resin RFQ template.

Common questions
What is Pro-fax SE012?
Pro-fax SE012 is a LyondellBasell low melt flow, electrical grade polypropylene copolymer for wire and cable. LyondellBasell lists oil well logging cables, data cables and heavier wall insulation as typical uses, with injection molding and wire and cable as processing methods. It is sold in North America.
Is Pro-fax SE012 a homopolymer or a copolymer?
A copolymer. LyondellBasell calls it a polypropylene copolymer and lists “Copolymer” among its attributes. Its published data does not say whether it is an impact or a random copolymer, so ask if your spec needs that detail.
What is the melt flow of Pro-fax SE012?
1.5 g/10 min, measured at 230°C / 2.16 kg, ISO 1133-1, per LyondellBasell’s technical data sheet. That is a typical value, not a specification limit.
Is Pro-fax SE012 nucleated or antistatic?
LyondellBasell’s product page and data sheet do not list a nucleating or antistatic agent for SE012. They describe good colorability, resistance to stress cracking and proven life in the presence of copper. Ask for the Product Stewardship Bulletin if you need the additive status confirmed.
Is Pro-fax SE012 sold in Europe, or renamed under Velogy?
LyondellBasell lists North America as its only availability region. Pro-fax SE012 is not among the grades renamed under Velogy; that rename covered grades made at the four European sites LyondellBasell sold to AEQUITA in May 2026. See our Velogy grade name lookup.
What is equivalent to Pro-fax SE012?
Grades to ask about include Pro-fax EP315J, LyondellBasell’s electrical grade PP copolymer for primary insulation, and Pro-fax SV258, a general extrusion impact copolymer at similar flow. Neither is identical. Wire and cable approvals usually name the compound, so any change needs your customer’s approval and a trial.
Is Pro-fax SE012 food-contact compliant?
LyondellBasell’s data sheet makes no food-contact statement. It refers to the Pro-fax SE012 Product Stewardship Bulletin (PSB) and Safety Data Sheet for regulatory compliance. Ask for the PSB for your exact use.
Can ResinBridge supply Pro-fax SE012?
We quote Pro-fax SE012 when our supply partners can source it. If they cannot, we say so up front and quote a matched alternative, named on the quote with its data sheet, so you can decide whether to trial it.
If your grade is not listed, tell us what you run. We source commodity, engineering and specialty resins.
