Low density OPE wax for CPVC compounds

About Low density OPE wax for CPVC compounds

CPVC compounds are prone to problems such as thermal decomposition, equipment sticking, and poor surface finish during production. Traditional lubricants often struggle to balance lubrication effectiveness with product performance. As a specialized additive, low-density oxidized polyethylene wax is the ideal lubrication solution for high-performance CPVC compounds.

Low-density oxidized wax is specifically designed for high-rigidity polymer systems, possessing a unique polar molecular structure and uniform molecular weight. Unlike ordinary PE waxes and paraffin waxes, it provides balanced internal and external lubrication, perfectly matching CPVC production formulations and effectively addressing common processing defects.

Uneven lubrication is a major problem in CPVC extrusion and granulation processes. Excessive internal lubrication reduces melt strength, while excessive external lubrication leads to uneven plasticization. This oxidized wax effectively solves these problems: moderate internal lubrication reduces melt viscosity and processing heat, preventing thermal degradation; stable external lubrication prevents material sticking, mold buildup, and demolding, ensuring smooth and continuous production.

Key Advantages in CPVC Compound Production:

1. Stable and Balanced Lubrication Performance

Achieving precise and balanced lubrication, avoiding both delayed plasticization and over-lubrication, greatly stabilizes the CPVC extrusion process and improves production consistency.

2. Enhanced Finished Product Surface Quality and Gloss

Uniform dispersion optimizes melt flow, eliminates surface defects, and gives CPVC products a smooth texture and high gloss.

3. Protection of CPVC Mechanical and Thermal Properties

Excellent compatibility with CPVC resin; it does not precipitate or migrate after use, fully maintaining the original high-temperature resistance and mechanical properties of the CPVC compound.

4. Wide Formulation Compatibility and High Cost-Effectiveness

This product is compatible with mainstream stabilizers such as calcium zinc and organotin compounds, offering a wide processing tolerance and stable batch quality, reducing formulation adjustment costs and product scrap rates.

Compared to traditional lubricants, low-density oxide wax provides more stable and professional lubrication for CPVC production. It optimizes processing efficiency while fully ensuring the overall performance of the finished product.
