The wood plastic special chlorinated polyethylene (CPE) developed by Bontecn Group China Co., Ltd. is a high-performance PVC modifier optimized for wood plastic composite materials. It mainly enhances the toughness, flame retardancy, and weather resistance of wood plastic through CPE.
Main performance and function:
1. Toughening and strengthening: CPE, as a rubber dispersed phase, can absorb impact energy by adding wood plastic matrix, suppress crack propagation, significantly improve material impact resistance, and is suitable for external force prone scenarios such as door and window profiles and panels.
2. Flame retardant and weather resistant: The chlorine containing structure endows it with self extinguishing properties, reduces the addition of flame retardants, and also resists UV aging in outdoor environments, ensuring the long-term stability of wood plastic products.
3. Cold and anti-corrosion: Maintain flexibility at low temperatures (below -30 ℃) and resist acid and alkali erosion, suitable for humid or high temperature difference environments.
Advantages of application in wood plastic:
1. Good compatibility: CPE is evenly mixed with polyethylene (PE) or polyvinyl chloride (PVC) based wood plastic, which can improve processing fluidity and enhance surface printing adhesion.
2. Cost effectiveness: Replace traditional toughening agents (such as elastomers), reduce production costs, and meet environmental requirements (free of heavy metals).
3. Typical scenario: Used for wood plastic panels, building decorative panels, etc., the addition amount is usually 5-10% of the substrate to ensure a balance between hardness and toughness and prevent brittle cracking.
In summary, wood plastic special CPE can achieve customized product performance and is a key additive for improving the comprehensive durability and safety of wood plastic.
