Light stabilizer HPT ingredients: methyl six phosphorus triamide

Light stabilizer HPT properties and uses

This product is colorless or light yellow transparent liquid. Slightly fishy astringency. 1.0253~1.0257g/cm3 density (20 ℃). Freezing point 27 ℃, boiling point 116~117℃ (1.48kPa). Refractive 1.4582~1.4589 (20 ℃). Solubility in polar and non-polar solvent, and dioctyl phthalate, dioctyl sebacate, dibutyl phosphite three benzoate plasticizers can be anything such as miscible.

Light stabilizer HPT are available as light stabilizers for PVC. Can provide products with good outdoor anti-aging performance, so with PVC high efficiency weather resistant agent said. Add 2~5 to the PVC film product, not only can significantly improve its weather resistance and cold resistance, and temperature can drop about 10 degrees Celsius and, in addition, this product can also be used as polyamide, polyurethane, urea-formaldehyde resin, PPS and other polymer materials good solvents.

Safety precautions: this product is toxic, not intended for contact with food products, and should avoid contact with the skin.

, Light stabilizer HPT main uses:

Can effective to absorption wavelength for 270-380 Nano of purple outside light, main for PVC, and polystyrene, and not saturated resin, and poly carbonated ester, and poly methyl acrylic methyl ester, and polyethylene, and ABS resin, and epoxy and cellulose resin,; applies Yu photographic material as color film, and color film, and color photo paper and polymer polymer, many field; special applies Yu colorless transparent and light products in the; for strong absorption force, high performance UV absorption agent.

Second, light stabilizers HPT salient features:

Super strong ultraviolet ray absorption; effectively prevent UV damage to the skin and cancer-and significantly improve product's anti-aging properties. Does not absorb visible light, is a colorless, transparent and light products preferred UV absorbers; not flammable, non-corrosive, good storage stability; and a variety of good compatibility of polymers, both effective anti-oxidant, anti-yellowing effect performance, and General antioxidant and; very high security.

Third, light stabilizers HPT chemical index:

Appearance: light yellow powder melting point: 138 c-141 c ash: ¡ü 0.05% volatile: 0.1% maximum transmittance: 460nm ≥ 95%;500 nm ≥ 97% solubility: soluble in solvents such as benzene, toluene, styrene, and slightly soluble in ethyl acetate, petroleum ether, insoluble in water

D, light stabilizers HPT usage:

Normal dosage for 0.1-0.5% in thin products, thick products for 0.05-0.2%. Amount added under other conditions: 0.05-0.3%.
