Ultra High Molecular Weight Functional Siloxane Additives in Polymers: Effects on Processing and Properties

Siloxane process additives are substances added to various manufacturing processes, particularly those involving polymers like plastics and rubbers, to enhance specific properties or facilitate processing. These additives can include various silicone-based compounds designed to improve characteristics such as mold release, surface quality, flow, and overall processing efficiency. They may also provide benefits such as reducing extruder torque, improving mold filling, and enhancing the final product’s durability and performance. Silicone process additives are crucial in optimizing manufacturing processes and achieving desired product outcomes.

Xiangxi ‘s silicone additive masterbatch is used in the plastics industry with small proportions to optimize the production process and properties of plastic products. All of them apply the newest, the most modern technology according to European standard first time represent in China. In Xiangxi, we offer 7 selections of silicone process additive masterbatch: Anti-abrasion additives, Anti-scratch additive, Anti-floating addtives, Anti- slip resistance additives, silicone feel additives slip silicone additive and silicone lubricants additives.

Silicone additive masterbatch functioning as lubricates

There are 2 benefits of silicone additive:

1.Internal Lubricants:

These are utilized to reduce friction among plastic components or between high molecular weight chains, effectively preventing the adhesion of molten plastic due to thermal catalysts.

2.External Lubricants:

These serve to prevent the adherence of plastic to the internal surfaces of cylinders, screws, and molds throughout the injection molding process.

Xiangxi offers complete ploymer silicone additives solutions for many markets and applications,such as with wide range of products developed for different applications:

1. Silicone Additive Solutions for Wire & Cable Applications

Our Silicone lubricant and mold release masterbatch are extensively employed in a wide range of cable materials, including LSZH flame-retardant polyolefin compounds, Locomotive, new-energy cable compounds, Flame retardant and non-flame retardant TPE cable compounds, radiation crosslinking compounds, electronic fine lines compound and high-speed extrusion cables compounds etc.These agents effectively enhance material flame retardancy and oxygen index, improve extrusion liquidity, and reduce viscosity, thereby significantly enhancing overall material processing performance. Also could be effectively solve the problem ofaccumulation at the die outlet of the extrusion process.

2. Silicone Additive Solutions for Automotive Applications

Our silicone anti-scratch masterbatch improves compatibility with automotive PP interiors (CO-PP/HO-PP), reducing phase segregation and preventing migration or exudation. This results in decreased fogging, VOCs, and odors, while enhancing long-lasting anti-scratch properties. It also improves quality, aging, hand feel, and reduces dust buildup. Suitable for a variety of automotive interior surfaces, including door panels, dashboards, center consoles, and instrument panels.

3. Silicone Additive Solutions for Footwear Applications

Our silicone anti-abrasion masterbatch is specially formulated for the footwear industry, suitable for EVA/PVC, TPR/TR, rubber, and TPU shoe soles. It significantly enhances abrasion resistance and reduces abrasion values in thermoplastics, making it effective for DIN, ASTM, NBS, AKRON, SATRA, and GB abrasion tests. It also improves liquidity and dispersibility, effectively addressing issues like black lines, bubbles, and mucous membranes.

4. Silicone Additive Solutions for Engineer Plastics Applications

Our silicone lubricants masterbatch enhances lubrication and liquidity in engineering compounds such as PA, PC, PET, and PBT. It reduces electricity consumption and screw torque during production, while also improving heating stability and lowering the friction coefficient of product surfaces. Additionally, it enhances smoothness, provides a silky tactile expression, and improves scratch resistance.

5. Silicone Additive Solutions for TPE Compounds

Our silicone feel and lubricants masterbatch is suitable for thermoplastic elastomers, aiding in demolding products from molds. It enhances fluidity, acting as internal and external lubrication during production. This improves the smoothness of product appearance and provides a better silky tactile expression. Additionally, it enhances fluidity and acts as internal and external lubrication during production.

6. Silicone Additive Solutions for Telecommunication Pipes

When our silicone masterbatch is added to the inner layer of HDPE Telecom pipes, it reduces friction coefficients, facilitating the blow of optic fiber cables over longer distances. The silicone core layer is extruded synchronously with the inner wall of the pipe, ensuring uniform distribution throughout. It maintains physical and mechanical performance equivalent to HDPE, with no peeling or separation, while providing permanent lubrication. This application is suitable for PLB HDPE telecom ducts, silicon core ducts, outdoor telecommunication optical fibers, optic fiber cables, and large pipeline systems.

7. Silicone Additive Solutions for Plastic Films

Our slip silicone masterbatch enhances anti-blocking and smoothness in PE system films, reducing friction coefficients for smoother surfaces and improved processing lubrication. Its special structure ensures compatibility with the matrix resin, with no precipitation and no impact on film transparency or suitability for food contact.

8. Silicone Additive Solutions for Home Applicances

Our silicone masterbatch is formulated for use with base materials such as PP, PA, and PC/ABS, resulting in a long-lasting, glossy piano-black finish on product surfaces. This enhances the appearance of appliances, automotive parts, and household items, while also providing exceptional scratch and mar resistance. It is well-suited for applications requiring spray-free high gloss materials.
