Sealing Grade PA Hot Melt Glue Pellets Oil Diesel Filter End Cap Adhesive Resin 135C Viscosity Stable
This sealing grade polyamide hot melt resin is engineered for filter makers who run continuous pleating and cap bonding lines. The pellet form melts evenly, holds a stable viscosity through a full shift and forms a resilient gasket like seal at the end cap seam of oil and diesel filters.

Selling Points
- Sealing grade flow: low melt viscosity wets the pleat ends and the cap knurl completely, closing micro channels that cause bypass and premature filter failure.
- Viscosity stability: the resin resists thermal degradation in the glue pot, so the bead width stays the same from the first filter to the last filter of the shift.
- Flexible seal: elongation above 300% absorbs vibration and thermal expansion of the filter can without cracking the seal.
- Fuel and oil resistance: tested against diesel, biodiesel blends, engine oil and coolant with no softening or swell.
- Low odor and low fume: improves the working environment on the pleating line.
