PVC tubing commonly used additive types and functions

PVC tubing commonly used additive types and functions
Additive type USES and functions
Heat stabilizer to prevent decomposition of PVC hoses, general but to improve thermal stability of resin by 10 times
Organic tin stabilizer used in pipes, pipe fittings, window and other hardware products
Calcium/zinc stabilizer is used for plasticizer and stabilizer for hard products that come in direct contact with food
Methyl tin and dotl composite stabilizer used in contact with food containers
Lead stabilizer has good electrical conductivity, not used for wire and cable of plasticizing ingredients
Barium/zinc stabilizer compared with barium cadmium stabilizers, are more likely to accept for the environment, therefore, used for molding products, profiles and wire coating plasticizer
Organic hindered phenol and phosphite ester used as stabilizer
All kinds of impact modifiers acrylic resin (ABS), chlorinated polyethylene, ethylene – vinyl acetate, etc
Processing AIDS is the most commonly used methyl acrylate and acrylic resin
Lubricant has inside outside lubricants, lubricants, generally there is a polar groups and the polar groups of surfactant
Plasticizer of PVC crystalline region plays a role of junction, amorphous area can accept a large amount of plasticizer, form a type of rubber materials. A small amount of plasticizer can provide special performance for special applications
Phthalic acid esters plasticizer of the most commonly used, because of environmental problems, some species (DOP), some countries in some areas has been banned
Fatty acid esters in Europe for fear of toxicity of DOP is has two acid two different nonyl ester etc instead of DOP
Citric acid ester for contact with food products
Benzoic acid esters used in anti fouling products
Chlorinated hydrocarbons with flame retardancy and good performance
Fatty alcohol esters to improve the flame retardancy, lower volatility, and make products with good flexibility at low temperature
Trimellitic anhydride reduce volatile, provide good performance at low temperature
Epoxy plasticizer reduce volatile
Polymer plasticizers reduce volatile
Packing in order to improve the rigidity, reduce cost and control the luster
Calcium carbonate is the most commonly used fillers
Clay can improve performance of burning
Glass fiber to improve the tensile strength and rigidity, but beneath extensibility
Talc increase tensile strength and rigidity, but beneath extensibility
Mica increase tensile strength and rigidity, but beneath extensibility
Special packing, paint color
Common packing, such as carbon black, titanium dioxide color
Light stability agent, the effect was to absorb ultraviolet light, carbon black and titanium dioxide can play a role of light stability agent. Benzotriazole derivatives of the commonly used as a light stabilizing agent. Some heat stabilizer and hindered amine light stabilizer has the special effect
Biological kill agent in ponchos, swimming pool liner, roof seal products such as add, often is compatible with PVC and other additives stability and weather resistance of arsenic compounds
