China PTFE-Free LYSI-704 Silicone Processing Lubricant for Wear-Resistant Engineering Plastics Manufacture and Factory

PTFE-Free LYSI-704 Silicone Processing Lubricant for Wear-Resistant Engineering Plastics

Silicone Masterbatch LYSI-704 is a pelletized formulation containing an ultra-high molecular weight siloxane polymer dispersed in PE. Featuring a unique siloxane structure, it is widely used as an anti-abrasion additive in modified engineering plastics such as PA, POM, and others. It serves as a sustainable alternative to conventional additives like PTFE-based lubricants and processing aids.

LYSI-704 offers comparable or superior wear resistance without PFAS-related concerns and requires a lower addition rate. When incorporated into PA66 reinforced with glass fibers, it effectively addresses the issue of fiber floating, improved surface quality and performance.

Description

Silicone Masterbatch LYSI-704 is a pelletized formulation with ultra-high molecular weight siloxane polymer dispersed in PE. It has special structure of siloxane and is widely used as an anti-wear additive for modified engineering plastics like PA, POM, and to form a lubricating layer on the surface, reduce the friction coefficient, improve the wear resistance, and have good compatibility, almost no impact on mechanical properties with a low addition, and also has the feature of improving float fibers issue.

Compared to conventional lower molecular weight Silicone / Siloxane additives, like Silicone oil, silicone fluids or other types of processing aids, SILIKE Silicone Masterbatch LYSI series are expected to give improved benefits, eg,. Less screw slippage, improved mold release, reduced die drool, a lower coefficient of friction, fewer paint and printing problems, and a broader range of performance capabilities.

Fundamental Parameters

Grade	LYSI-704
Appearance	White pellet
Silicone content (%)	/
Resin base	PE
Melt index (190℃, 2.16KG) g/10min	2~6
Dosage % (w/w)	3~5

Benefits

(1) Improve processing properties, including less extruder torque, better molding filling & release, better internal and external lubricity properties, and improve output greatly;

(2) Improve surface quality like surface slip, lower Coefficient of friction, Greater abrasion resistance;

(3) Have a special structure of siloxane, will not get sticky, have low odor, no precipitation, are eco-friendly, and have low VOCs;

(4) Enhance stability compared with traditional processing aids or lubricants;

(5) Meet RoHS and REACH.

Applications

(1) PA (Polyamide, e.g., PA6, Nylon PA66), POM, and other engineering plastics

(2) Other PE-compatible plastics

How to use

SILIKE LYSI series silicone masterbatch may be processed in the same way as the resin carrier on which they based. It can be used in classical melt blending process like Single /Twin screw extruder, injection molding. A physical blend with virgin polymer pellets is recommended .

Recommend dosage

When added to Nylon, POM or similar thermoplastic at 0.2 to 1%, improved processing and flow of the resin is expected, including better mold filling, less extruder torque, internal lubricants, mold release and faster throughput; At a higher addition level, 2~5%, improved surface properties are expected, including lubricity, slip, lower coefficient of friction and greater mar/scratch and abrasion resistance.

Package
