| DSK-1010 Antioxidant | DSK-1010 is an antioxidant that does not change color,does not pollute,heat-resistant oxygen aging, heat-resistant water extraction,and is not volatile.It is widely used in polypropylene,polyethylene, polyoxymethylene,ABS resin and various synthetic rubber products,which can significantly extend the service life of plastic products.When this product is used together with auxiliary antioxidants,it can significantly improve its heat resistance.It is one of the products with better performance among the current antioxidants,and the general dosage is 0.1%~0.5%. |
| DSK-1076 Antioxidant | DSK-1076 is an efficient and environmentally friendly hindered phenolic antioxidant,which has good compatibility with most polymers.It has good prevention of discoloration caused by light and heat and has good heat resistance and water extraction resistance.It has the advantages of high antioxidant performance,no coloringno pollution,washing resistance,and low volatility.It is widely used in polyeth- ylene,polypropylene,polystyrene,ABS resin,polyvinyl chloride,nylon,polyester,polyurethane,cellulose plastic,and various rubber products.Combined use with antioxidants AT-168,DLTDP,etc.can exert a synergistic effect andimprove the antioxidant effect.The dosage is generally 0.1%~0.5%. |
| DSK-168 Antioxidant | DSK-168 is an auxiliary antioxidant,compounded with the main antioxidant DSK-1010 or DSK-1076,it has a good synergistic effect,no coloring,no pollution,and good volatility resistance.It is widely used in polymer materials such as polyolefins,styrene monomers and copolymerselastomers,adhesives, engineering plastics(such as:PE,PP,PVC,PS,polyamide,polycarbonate,ABS). |
| DSK-626 | K-626 is an efficient organic phosphate auxiliary antioxidant,which is characterized by anti-yellowing, high transparency,and is a low volatile organic synthetic antioxidant Polymerization inhibitor,has good compatibility with most polymers.It has a good protective effect on the color of the polymer.Generally not used alone,it is often used in combination with phenolic main antioxidants such as antioxidant DSK-1010, which can improve the thermal stability of the polymer processing process.It is widely used in the synthesis and processing of various plastics such as polypropylene,polyethylene,ABS,polycarbonate fiber and polyester resin. |
| DSK-3114 Trifunctional Hindered Phenolic Antioxidant | DSK-3114 is a hindered phenolic antioxidant with trifunctional groups,which does not pollute or color.Due to the high molecular weight and melting point,it has very low volatity,low migration,and good water extraction resistance,which can give plastics excellent heat resistance and photooxidation resistance.This product can be used for food-contact polyolefin products(fatty and non-fat foods can be contacted).It is suitable for polyethylene,polypropylene,polystyrene,ABS resin,polyester,nylon,polyvinyl chloride, polyurethane,cellulose plastic and synthetic rubber,and the effect is particularly remarkable in polyolefin. The general dosage is 0.1~0.25%,and it has a synergistic effect when used with ultraviolet absorbers or phosphates,which can further improve thelight and heat stability. |
