This table shows the plastic most often used in automotive applications. Don't see the symbol on this table? Click here for a more complete listing.
The plastics with the yellow background are thermoset plastics.
|Symbol & Type||How to identify||Typical Usage||Suggested Repair Method||Repair Tips|
|DCPD, PDCPD, Metton (Polydicyclopentadiene)||Rigid Material, no fibers, dark gray in color.||Large truck and tractor panels and hoods||Method AD-1 w/ 2510 PlastiFix two-part methacrylate adhesive||Use backing plate over holes, layer in fiberglass cloth for extra strength.|
|PUR, RIM, RRIM Thermoset polyurethane||Usually flexible, maybe yellow or gray, bubbles and smokes when attempting to melt.||Flexible bumper covers (especially on domestics), filler panels, rocker panel covers, snowmobile cowls.||Method AW-3 w/ urethane (R01) rod or Method AW-2 with FiberFlex||Don't try to melt the base material! Just melt the rod into the v-groove like a hot melt glue.|
|SMC, UP, FRP, Fiberglass||Rigid, polyester matrix reinforced with glass fibers, sands finely||Rigid body panels, fenders, hoods, deck lids, header panels, spoilers||Method AD-1 - two-part epoxy repair with fiberglass reinforcement.||Use backing plate over holes, layer in fiberglass cloth for extra strength.|
|XPE, XLPE, PE-Xb, PEX, Crosslinked Polyethylene||Semi-Flexible, waxy or greasy feel, softens when heated but does not melt||Gas tanks, kayaks, canoes, trash cans, use is declining||Method AW-3 with polyethylene rod (R04 series). Use as a hot melt adhesive.||Applying filler or painting is difficult or impossible. Browns when heated.|
|ABS (Acrylonitrile Butadiene Styrene)||Rigid, often white but may be molded in any color, sands finely. Very pungent odor when heated.||Instrument panels, grilles, trim moldings, consoles, armrest supports, street bike fairings.||Method AW-1 or N2-1 w/ ABS rod (R03 series), or Method AD-1 Two-Part epoxy repair.||PlastiFix is an optimal repair method. Weld repairs may be backed with epoxy for extra strength.|
|HDPE Polyethylene||Semi-flexible, melts & smears when grinding, usually semi-translucent, waxy or greasy feel.||Overflow tanks, inner fender panels, water storage tanks, gas tanks, kayaks, canoes, playground equipment.||Method AW-1 or N2-1 with high density polyethylene rod (R12 series).||Applying filler or painting is nearly impossible.|
|PA, PA-6, PA Polyamide (Nylon)||Semirigid or rigid, sands finely||Radiator tanks, headlamp bezels, exterior trim finish parts, mirrors, plastic engine parts||Method AW-1 with nylon rod (R06 series).||Preheat plastic with heat gun before welding, mix rod completely with base material.|
|PBT Polybutylene terphthalate||Semi-rigid or rigid, sands finely.||Automotive panels, electrical connectors, under-hood parts.||Method AW-1 or N2-1 with PBT rod (R08 series).||Crystalline type plastic. Has low coefficient of friction. Use heavy pressure and reinforce with 2045 mesh.|
|PC + ABS Pulse (Polycarbonate & ABS)||Rigid, sands finely, usually dark in color||Door skins (Saturn), instrument panels, street bike fairings||Method AW-1 or N2-1 with Polycarbonate rod (R07 series), or Method AD-1 adhesive repair||Preheat plastic with heat gun before welding.|
|PC + PBT, Xenoy (Polycarbonate blend), SLX||Rigid, sands finely, usually dark in color||Bumper covers (primarily Ford products, 84-95 Taurus, Aerostar, some Mercedes and Hyundai's)||Method AW-1 or N2-1 with polycarbonate rod (R07 series), or Method AD-1 adhesive repairs.||Preheat plastic with heat gun before welding.|
|PE / LDPE Polyethylene||Semi-flexible, melts & smears when grinding, usually semi-translucent, waxy or greasy feel. Smells like a candle when melting.||Overflow tanks, inner fender panels, water storage tanks, gas tanks, kayaks, canoes, playground equipment, trash cans.||Method AW-1 or N2-1 with low density polyethylene rod (R04 series).||Applying filler or painting is nearly impossible.|
|PETE, PET Polyethylene Terephthalate||Flexible, strong||Soda bottles, various yarn fibers, headliners, fuse boxes, door panels||Method AW-1 or N2-1 with PET rod (R13 series).||Can't make as strong as original part; manufactured in crisscrossed layers and can't be duplicated.|
|PP Polypropylene||Semi-flexible, melts & smears when grinding, waxy or greasy feel, usually a bit stiffer than PE's||Bumper covers (usually blended with EPDM), inner fenders, radiator shrouds, gas tanks, battery cases, interior panels||Method AW-1 or N2-1 with polypropylene rod (R02 series) or method AW-2 with FiberFlex (R10 series).||Use 1060FP Filler Prep adhesion promoter when applying two-part epoxy filler|
|PPE, PPE+PS Polyphenylene Ether||Semi-rigid, sands finely, usually off-white or black in color||Fenders, exterior trim, rear hatch panels||Method AW-1 or N2-1 with PPR+PS rod (R08 series) or AD-1||Preheat plastic with heat gun before welding.|
|PPO + PA Noryl GTX (Nylon blend)||Semi-rigid, sands finely, usually off-white in color.||Fenders (Saturn & GM), exterior trim||Method AW-1 or N2-1 with GTX rod (R15 series) or nylon rod (R06 series).||Preheat plastic with heat gun before welding.|
|PVC Polyvinyl Chloride||Rigid, sands finely, Usually white or gray but can be made any color||Pipe, siding, window frames, decking, gutters, speed bumps||Method AW-1 or N2-1 with PVC rod (R09 series).|
|TPE Thermoplastic Elastomer||Semi-flexible, usually black or gray, melts & smears when grinding.||Bumper covers, filler panels, underhood parts.||Method AW-2 with FiberFlex (R10 series).||Use 1060FP Filler Prep Adhesion Promoter before applying two-part epoxy filler.|
|TPO, EPM, TEO Thermoplastic Olefin||Semiflexible, usually black or gray in color, melts & smears when grinding||Bumper covers, air dams, grilles, interior parts, instrument panels, snowmobile cowls.||Method AW-1 or N2-1 w/ polypropylene rod (R02 series) or TPO rod (R05 series), or method AW-2 w/ FiberFlex rod (R10 series).||Use 1060FP Filler Prep Adhesion Promoter when applying two-part epoxy filler|
|TPU, TPUR - Thermoplastic Polyurethane||Flexible, sands finely||Bumper covers, soft filler panels, gravel deflectors, rocker panel covers||Method AW-3 w/ polyurethane rod (R01 series) or Method AW-2 with FiberFlex rod (R10 series).|

Plastic Identification Using the Float Test and Burn Test
The float test and burn test have been around for years. It's a good test for ruling out certain plastics, but difficult to specifically identify a plastic. CLICK HERE to see the test results on various plastics.
