External Lubricants additives : Ethylenebis Stearamide EBS Powder 99% Min
External lubricants are incompatible with PVC compounds (They do not dissolve in PVC or disperse homogeneously) at processing temperatures. They act as an interface between the PVC compounds and the metal surfaces of the processing equipment and prevent the molten PVC from adhering to the processing equipment. The behaviour of PVC within the processing equipment depends on the composition of the external lubricant. In addition, these materials reduce the friction between the polymer particles during the plasticizing process, thereby preventing temperature increase.
Physical and chemical properties: white to light yellow high melting point wax, with lubrication, dispersion, light, stripping, smooth, anti-stick and anti-static effect, as well as the pigment and filler has excellent coupling effect and dispersion, In most solvents and water, soluble in hot xylene, chloroform, butanol and other high boiling solvent. Flash point of about 285 ℃, the relative density of 0.98 (25 ℃).
1. Little granule(20 meshes) : Used as a kind of lubricating agent of ABS, steroplasm PVC,AS,PA,PP and plastic-wood; blocking agent of LDPE and LLDPE; slipping agent and anti-bonding agent of PS; release agent,dispersing and lubricating agent of PET,PBT and POM; Dispersing agent of antiflaming master batch –EVA and varnish lubricating of rubber(tube,plate and car floor mat.
2. Powdery (125 meshes): Can be used as dispersant of plastics(ABS,PS),masterbatch and chemicalfiber(Polypropylene fiber&terylene), light dispersant of mineral filler and flame retardant and lubricant of modified material-ABS etc.
3. Pulverized(200 meshes): Used for cerate and dispersant of printing ink and coating paint; pigment grinding adjuvant and dispersant in coating industries as well as dispersant of carbon black in chemical fiber.
4. Fine powdery(325 meshes): Can be used for dispersant and difusion in toner for color matching as well as modifier and lubricating dispersant of ultrafine powder. So as to improve vividness and glossiness of the product and processing efficiency.
