UV- 770: 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 photostability for thick sections, but can also be used for high surface area items such as films and tapes. It is recommended to setUV- 770 for polypropylene, impact-modified PP (TPO), EPDM, polystyrene, impact polystyrene, ABS, SAN, ASA, polyurethane, is also used in polyamides and polyacetals. The recommended concentration range is 0.1-1.0%, depending on the substrate, processing conditions and application.
UV- 622: is a low Poly hindered amine light stabilizer (HALS). Furthermore, it is effective as an antioxidant and makes an important contribution 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,: Especially effective for cold molded high resilience foam, catalyst with low odor gel and foaming balance
LE-310: A low-odor reactive gel catalyst for large sponges, a new type of low VOC amine gel catalyst, the amine content exceeds 95%
LE-530: Reactive gel catalyst, used in various polyurethane foam products
DPA: low-odor gel catalyst, outstanding balance and versatility to provide good fluidity
TAP 1-methyl-4-(2-dimethylaminoethyl)piperazine: Excellent trimerization catalyst to improve fluidity
DMDEE (2,2′-dimorpholine diethyl ether): Strong foaming catalyst, providing a stable prepolymer system
DMAEE: low-density full-water rigid foam and low-density semi-rigid foam
BDMAEE bis-(2-dimethylaminoethyl) ether: Efficient foaming catalyst
BDMA (N,N-Dimethylbenzylamine): Polyurethane rigid foam catalyst, epoxy accelerator
DMEA (N,N’-dimethylethanolamine): Neutralize acid in some hard foam systems,
PMDETA (pentamethyldiethylenetriamine): It is especially effective for HCFC/water foaming hard foam, similar to PC5
