Lubricants

Description

VALEX's PVC lubricants reduce friction and improve flow in plastic processing. Our specialized additives prevent sticking, enhance mold release, and boost production efficiency for extrusion and molding. Ideal for Algerian manufacturers seeking smoother surfaces and energy savings in PVC production.

Acrylic processing aid

The addition of processing aid significantly reduces fusion time and enhances melt homogeneity, enabling higher processing temperatures and increased production rates while ensuring excellent surface quality. This low molecular weight additive improves melt strength and reduces plate-out. Key benefits include eliminating melt fractures, enhancing surface finish, minimizing die buildup, increasing production capacity, reducing gels, improving processability, and facilitating the use of recycled or regrind resins.

Stearic acid

Stearic acid is a versatile additive in PVC processing, functioning as both an internal lubricant (0.2-0.5 phr) to improve melt flow and reduce viscosity and an external lubricant (0.5-1.0 phr) to prevent adhesion to processing equipment. It enhances fusion characteristics in rigid PVC applications like pipes and profiles while improving mold release in flexible PVC products such as cables and films. This cost-effective additive works synergistically with calcium/zinc stabilizers, reduces plate-out, and optimizes energy efficiency during processing, though excessive use (>1.0 phr) should be avoided to prevent blooming or surface defects.

Pe wax (polyethylene wax)

Polyethylene Wax (PE Wax)

is a versatile additive that enhances processing and performance in plastics like PVC, PP, and rubber. It acts as an effective lubricant, improving mold release, surface gloss, and flow properties while offering excellent heat and chemical resistance. Widely used in PVC products, masterbatches, coatings, adhesives, and more, PE Wax provides both internal and external lubrication for optimal processing efficiency.

Calcium stearate

Calcium stearate is a white, odorless powder widely used as a multifunctional additive in polymers and other industries. As a metallic soap of stearic acid, it serves as an effective heat stabilizer and lubricant in PVC processing, where it controls melt flow and prevents degradation. This cost-effective material also functions as a release agent in plastic and rubber production, and as an anti-caking agent in pharmaceuticals and cosmetics. With excellent thermal stability (melting point ~150°C) and hydrophobic properties, calcium stearate is particularly valuable for rigid PVC applications like pipes and profiles, while also finding use in paper coatings, construction materials, and food-grade applications.
