plastic external lubricants in the application of other plastic

Polyamide in the application:
Plastic and external lubricants , such reinforcements and uniform distribution of the pigment in the polyamide . Usual dose is 0.2-0.5% . In injection molding polyamide , ease of demolding and lubricants depending on the effect of crystallinity , as they improve flow properties and  vegetable stearic acid release properties , and thus very suitable for molding , injection molding and temperature make it possible to save time .
Thermosetting plastics in the application:
Thermosetting plastics in the acrylic processing  production and processing to a lubricant and release agent . These products must be accurate and consistent with each other . Use a compatible lubricants can improve mobility , the outer material and the lubricant can reduce the adhesion of the hot parts of the machine , thus improving the release effect . Plastics and external lubricants to a very strong effect and internal mold release lubricant combined to provide a greater allowable operating range . They are neither the product nor plasticized migration .
Application of the iron oxide yellow  thermoplastic polyurethane : Thermoplastic polyurethane (TPU) at just after processing is very viscous . Results Injection difficult stripping and stacking adhesions. Use plastic external lubricants can give a very good release effect and will not migrate .
