Thermoplastic PA Hot Melt Adhesive Pellet Automotive Filter Cap Bonding 150C Heat Resistant Compound
A high heat thermoplastic polyamide compound in pellet form for automotive oil and diesel filter cap bonding. The 150 °C softening point keeps the bonded cap rigid in hot engine bays, on turbocharged diesel engines and in filters that see repeated thermal cycling between cold start and full load.

Selling Points
- Heat resistant bond: the thermoplastic matrix resists creep at 150 °C, which suits filters mounted close to the exhaust manifold or on turbo diesel engines.
- Vibration tolerance: keeps a flexible but firm joint under engine vibration and pressure pulsation, so the cap will not lift off the media pack.
- Wide substrate range: bonds steel, aluminum, stainless steel, polyamide and phenolic caps to cellulose, synthetic and glass fiber media.
- Long service life: no adhesive aging or embrittlement in hot oil, extending filter life and reducing warranty claims.
- Reprocessable: as a thermoplastic, the compound softens again with heat and supports rework and recycling of production scrap.

FAQ
What makes it different from a standard PA pellet? The higher softening point and the modified polyamide backbone give a joint that holds at 150 °C in continuous service, which a 125 °C grade cannot guarantee.
Can it run on an existing glue pot? Yes, provided the pot can reach 200 °C and the nozzle or roller is rated for that temperature.
