ABS resin antioxidant
At present, the antioxidant of ABS resin is almost equal to the number of antioxidants of PP. Like IPS, it contains unsaturated double bonds of butadiene, so it is also sensitive to oxidation. Moreover, the number of unsaturated double bonds of ABS resin antioxidant is higher than that of modified PS. About 20%, because ABS has been in engineering plastics, its price is high and its application is wide. Therefore, adding antioxidants is particularly necessary.
The commonly used antioxidants for ABS resin are alkyl bisphenol, 1076, and phosphite. In order to improve the use effect, the phosphite can be used with the phenolic antioxidant.
Antioxidant 1076: Chemical Name:
Chinese beta (3,5- tert butyl -4- hydroxyphenyl) propionate is eighteen alcohol ester
CAS NO.:2082-79-3
Physical and chemical properties: This product is free from pollution, heat resistant and water resistant, soluble in benzene, acetone, cyclohexane and so on, slightly soluble in methanol, insoluble in water. This product is basically nontoxic.
Routine detection: appearance: white powder or particle; melting point: 50~55 C; ash <0.10%; volatile <0.50%; transmittance: 425nm is greater than 96%, 500nm is greater than 98%; content is greater than 98%.
Use: the product with antioxidant 168, and DLTDP, synergistic effect, thermal degradation and oxidative degradation of the polymer can be effectively suppressed, the products are widely used in polyethylene, polypropylene, poly formaldehyde, ABS resin, polystyrene, polyvinyl alcohol, engineering plastics, synthetic rubber and petroleum products, the general dosage is 0.1% ~ 0.5%.
Packing and storage: the paper plastic composite bag with plastic bags lined with plastic bags, each bag net weight 20kg, can also be designed according to customer requirements. The proposed storage time is 12 months in a dry and cool environment under the general chemical storage.
Phosphite belongs to auxiliary antioxidant, plays an important role in the antioxidant system, it has the outstanding ability of decomposing hydrogen peroxide (which is not the main antioxidant hindered phenol), but also good color protection ability, can be hindered phenolic antioxidants are dyed after bleaching light oxidation group. In addition, it can also improve the processing temperature of the polymer, and have a good synergy with the light stabilizer.
Triphenyl phosphite (antioxidant, stabilizer TPPi)
Packing method: net weight of 200KG/galvanized iron bucket (a small cabinet to hold 16 tons), 1000KG/IB (a small container with 18 tons) or 23 tons of it.
Port of shipment: Shanghai port
Price quotation validity: 15 days
Warehouse time: within 15 days (customs clearance)
Export rights: our own right to import and export.
Triphenyl phosphite (TPPi antioxidants, stabilizer) is mainly used in PVC, polyethylene, polypropylene, polystyrene, polyester, abs resin, epoxy resin, synthetic rubber antioxidant stabilizer, used in polyvinyl chloride (PVC) products as a chelating agent.
In the PVC formulation, phosphite ester is generally considered as the main chelating agent. When it is used alone, it has no obvious stabilizing effect. However, when combined with metal soap, it can complexate metal chlorides, improve heat resistance and weather resistance, and maintain transparency. It can also be used with organotin and epoxy compounds to show synergistic effects. It can reduce the amount of the main stabilizers, especially the expensive organotin stabilizers. Organo phosphite is widely used in liquid compound stabilizer. It accounts for about 10%~30% of the total amount. It has been widely applied in the formulation of PVC products, especially in transparent products, and its dosage is generally 0. 3~1.0phr.
Physical properties of liquid phosphite: carbon based -4, 4- two different fork - fatty alcohol - phosphate chelating polymer compound is corresponding to an efficient auxiliary heat stabilizer in high mixing, extrusion, calendering, blown film, cast, coating, improve the color and thermal stability of polymer processing field using dip in the most important feature of this product is that environmental protection does not contain free phenol, nonyl phenol, bisphenol A, mainly used for mixed liquid calcium zinc composite and composite powder, calcium zinc composite organic tin, organic rare earth, can also be combined with other stabilizers used mainly for synergistic auxiliary thermal stability, excellent out of. The introduction of anti ultraviolet aging and UV absorption, in addition to have excellent thermal stability, light stability and weather resistance are out of rhythm. It is an excellent chelating polymer.
Phosphite is a new organic ester containing phosphorus antioxidant. It is mainly used as auxiliary antioxidant for polyethylene, polypropylene, polyvinyl chloride, ABS resin and polyester resins. It is to prevent oxidation, improve the color has a prominent effect; it has high thermal stability, weatherability and stability to hydrolysis resistance, and good processing stability. Because of its pentaerythritol structure and high molecular weight characteristics, this product is highly suitable for the application of polymerized materials that require high temperature processing. Because of its trivalent phosphorus content, the antioxidant effect is more prominent and efficient. The product has good oxygen resistance and prevents "zinc burning", and has good lubricity.
This product does not contain phenol and bisphenol A, and is safe and nontoxic. It is in line with the latest market regulations and development trend. It meets the requirements of EU RoHS and WEEE instructions and can be used in food packaging materials. It is mainly applied to ABS, PS, HIPS, NBR, SBS, PP, PE, LLDPE, PVC, PC, PA, PC, SBS, amide fiber, polyester fiber, adhesive, coating, ink and compound auxiliaries. It is used for compounding calcium zinc stabilizer as antioxidant and auxiliary stabilizer.
Other such as 1010, DLTP, 2246, 264, DNP, metal zinc and so on can also be used as the antioxidant of ABS resin.
