UV- 770: It is bis(2,2,6,6,-tetramethyl-4-piperidinyl) sebacate. It is a low molecular weight hindered amine light stabilizer (HALS) used in applications requiring particularly high light stability. It provides excellent light stability for thick parts but can also be used on high surface area items such as films and tapes. It is recommended to use UV- 770 for polypropylene, impact modified PP (TPO), EPDM, polystyrene, impact polystyrene, ABS, SAN, ASA, polyurethane, is also used in polyamides and polyacetals. Recommended concentration range is 0.1-1.0%, depending on substrate, processing conditions and application.
UV- 622: is a low Polyhedred amine light stabilizers (HALS). In addition, it is effective as an antioxidant and contributes significantly to the long-term thermal stability of polyolefins and tackifier resins. Due to its high molecular weight oligomeric structure, it is suitable for all applications requiring low volatility and minimal migration. Its application areas include polyolefins (PP, PE), olefin copolymers (such as EVA) and blends of polypropylene and elastomers. In addition, : Low odor catalyst for packaging foam and molded foam on vinyl skins. Good balance of foaming and gelling
ZR-40 (pentamethyldipropylenediamine): Particularly effective for cold molded high-resilience foams, low-odor gel and foaming catalyst with good balance
LE-310: Low odor reactive gel catalyst applied to large sponges, new lowVOC amine gel catalyst, amine content exceeds 95%
LE-530: Reactive gel catalyst, used in various polyurethane foam products
DPA: Low-odor gel catalyst, outstanding balance and versatility provide good fluidity
TAP 1-methyl-4-(2-dimethylaminoethyl)piperazine: Excellent trimerization catalyst that can improve fluidity
DMDEE (2,2′-dimorpholindiethyl ether): Strong foaming catalyst, providing stable prepolymer system
DMAEE: low-density full-water rigid foam and low-density semi-rigid foam
BDMAEE bis-(2-dimethylaminoethyl) ether：High-efficiency foaming catalyst
BDMA (N,N-dimethylbenzylamine)：Polyurethane rigid foam catalyst, epoxy accelerator
DMEA (N,N’-dimethylethanolamine): Neutralizes acids in some rigid foam systems,
PMDETA (pentamethyldiethylenetriamine): Particularly effective for HCFC/water foamed hard foam, similar to PC5
