Light stabilizer：
PVC products are mostly exposed to sunlight and other kinds of light. Adding a certain amount of light stabilizer according to the application environment of the product can prevent and delay its decomposition and aging, and prolong the service life of the product.
Light stabilizers can be roughly divided into four categories:
(1) Light shielding agent. For example, titanium white and carbon black can block ultraviolet rays from entering the interior of the profile to prevent the photodegradation of the polymer from proceeding. For example, the aging resistance of LDPE sheet with 2% carbon black is 20 times higher than that of LDPE sheet without carbon black. Titanium dioxide can greatly improve the aging resistance of the profiles. Rutile type titanium dioxide should be used for titanium dioxide, and the usage amount in PVC plastic door and window profiles is 3-6 parts.
(2) Ultraviolet absorber. It can strongly absorb 280-400nm ultraviolet light and convert it into visible light or heat. Commonly used products are UV-531, UV-327, UV-326, UV-p, etc. The dosage is generally 0.1 to 0.5%. But the price is higher.
(3) Quenching agent. The main purpose is to eliminate the energy of the excited polymer molecule and return it to the ground state. Specific varieties are nickel and cobalt complexes, including light stabilizer 2002 and light stabilizer 1084. Generally used in conjunction with other light stabilizers, the dosage is 0.1-0.5%.
(4) Radical scavenger. It is an efficient light stabilizer, which captures the free radicals decomposed by photodegradation and terminates the degradation reaction. Generally used in LDPE agricultural film. The main varieties are: light stabilizer GW-540, GW-544, CW-310, BW-10LD, light stabilizer 744, light stabilizer 622, light stabilizer 944, etc. The dosage is 0.02-0.5%.
Application:
DOTP can be widely used in artificial leather,PU,PVC cable materials,plastic film,plastic sandals,foam sandals,seals of windows and doors,PVC profiles,soft board,all kinds of rigid pipe,decorative materials,foam hard board which all use the plasticizers,it can reduce the production cost of 30%.it is the main environment-friendly products in present market,meets the EU environmental standards(ROHS,REACH).DOTP is acknowledged by all over the world,is a non-toxic product can be applied in plastic production related to food and toys.
Shelf Life:
Original characteristics remain intact for 24 months,if kept in recommended storage.
Safety:
The MSDS can be provided on inquiry.
