Heat Stabilizers

Based on 23 products - Last update on the Jun 26, 2025

Heat stabilizers provide excellent long-term thermal protection with minimal impact on initial adhesive properties. They prove essential in automotive under-hood components, electronic assemblies, and industrial maintenance applications. 

Types include metal carboxylates, phenolic compounds, phosphite compounds, and synergistic stabilizer packages. Recent innovations focus on polymeric stabilizers with reduced migration potential addressing concerns about additive leaching and the development of non-toxic alternatives to traditional metal-based stabilizers.

Kanamoll- 620

by KLJ Group

Kanamoll- 620 by KLJ Group is an epoxidized soyabean oil grade. It acts as a good hydrochloric acid scavenger and as a secondary heat & light stabilizer. It also acts as co-stabilizing internal lubricant in rigid PVC formulations and as a plasticizer. It is recommended for adhesives and sealants. It is compatible with PVC, PVA, nitro cellulose and chlorinated rubber etc. It provides improved adhesion, toughness, glossiness, non-toxicity, cost reduction, environmental friendliness and chemical resistance. Recommended dosage of this grade for plasticized PVC is 2-5 PHR and for rigid PVC is 1-3 PHR. Kanamoll- 620 is approved by REACH.

Irganox® B 612

by BASF

Irganox® B 612 by BASF is a blend of 66.7% Irgafox® 168 and 33.3% Irganox® 565. Acts as a processing and long-term thermal stabilizer. Maintains original melt flow and offers low color formation. Provides long-term-thermal stability. Irgafox® 168, an organic phosphite of low volatility and particularly resistant to hydrolysis, protects the polymers which are prone to oxidation. Irganox® 565, a hindered phenolic antioxidant, contributes synergistically to polymer stabilization during processing and provides long-term thermal stability by preventing thermo-oxidative degradation. Irganox® B 612 is compatible with styrene homo- and copolymers, polyolefin homo- and copolymer, elastomers such as BR, IR, NBR, SBS, SIS, SEBS, SBR, EPDM, and NR. Its recommended dosage is 0.3-1.0%. It is registered in Australia, Canada, China, EU, Japan, Korea, Philippines and USA.
