Polyamide (PA) Hot Melt Adhesives
The high strength high temperature family — polyamide hot melts for bonds that have to hold when the part gets hot, cold or oily.

View Grade DataWhat This Category Is For
Polyamide hot melt adhesives are made from renewable raw materials such as castor or rape seed oil. They carry outstanding properties for bonds with higher requirements: very high heat stability, and the same reliability at low temperature. Special polyamide hot melts are capable of passing the temperature tests from -45 C to +135 C that are required in the electrical and electronic sector for the automobile industry, and they resist many chemicals and softeners. United Industry supplies polyamide hot melts in granule, powder and film form.
Core Advantages
- Very high heat stability compared with polyester and polyolefin hot melts
- Reliable at low temperature as well — special grades pass -45 C to +135 C testing
- Resistant to many chemicals and softeners
- Based on renewable raw materials such as castor and rape seed oil
- Available as granule, powder and film so one chemistry covers several processes
What Goes Wrong Without The Right Grade
Bonds that soften at service temperature and let the assembly move
Adhesives that go brittle below zero and crack in transport or in winter service
Softeners and plasticisers migrating out of the substrate and attacking the bond line
Encapsulation that has to survive an automotive temperature cycle test
Who Buys This Category
- Automotive electronics and sensor assemblers
- Low pressure moulding houses
- Filter element manufacturers
- Shoe material converters bonding counters and linings
- Textile laminators needing maximum peel strength
Where It Is Used
- Low pressure injection moulding in the electrical and automobile industries
- Coating of insulating materials
- Fixing technical components
- Filter end cap bonding
- Shoe counter and lining bonding
- Textile lamination where peel strength decides
Application Notes Using These Grades
Encapsulating A Tyre Pressure Monitoring Sensor With Black Polyamide Resin
A TPMS module has to survive wheel-well temperature swings, road salt and constant vibration, with a battery and a radio on the same small board. Low pressure moulding with black polyamide resin seals all of it in one shot.
Application NoteSealing A Connector And Moulding Strain Relief In One Operation
Hot melts are used for sealing the plug and also for cable strain relief. Doing both in one low pressure shot removes a whole assembly step.
Application NoteBonding Filter Media To End Caps With High Viscosity Polyamide Resin
Filter adhesives fail in a specific way: the adhesive wicks into the pleats and leaves the joint starved. A viscosity of 18000 mPa.s is the answer to that.
Polyamide (PA) Hot Melt Adhesives FAQ
What makes polyamide different from polyester hot melts
Heat stability. Polyamide holds its strength far higher up the temperature scale, and special grades are qualified against the -45 C to +135 C tests used in automotive electronics.
Is polyamide hot melt made from petrochemicals
Our polyamide hot melts are made from renewable raw materials such as castor or rape seed oil.
Which forms are available
Granule, powder and film.
Does polyamide resist plasticisers
Polyamide hot melts are described as resistant to many chemicals and softeners, which is one reason they are used on PVC and plasticised substrates.
Which grade should I start with
Tell us the process — moulding, lamination or counter bonding — and the service temperature. That pair decides the grade faster than any data sheet.
