Modified Plastic Extrusion Methods
We often use a variety of modification methods together to enable the custom plastic extrusion products to have a suitable and stable quality to meet the specific working environment in plastic extruding processing.
1, Reinforcement: by adding glass fiber, carbon fiber, mica powder, and other fibrous or flake fillers to achieve the purpose of increasing the rigidity and strength of the material, such as glass fiber reinforced nylon used in power tools.
2, Toughening: by adding rubber, thermoplastic elastomer, and other substances in the plastic to improve its toughness/impact strength, such as automotive, home appliances, and industrial use of common toughened polypropylene, etc.
3, Blending: two or more incompletely compatible polymer materials are uniformly mixed into a macro-compatible, micro-phase mixture to meet certain requirements for physical and mechanical properties, optical properties, processing properties, etc. method.
4, Alloy: similar to the blend, but the components are compatible with each other, easy to form a homogeneous system, and can obtain certain properties that can not be achieved by a single component, such as PC/ABS alloy, or PS modified PPO, etc.
5, Filling: by adding fillers in plastics to improve the physical and mechanical properties or reduce costs.
6, Other modifications: such as the use of conductive fillers to reduce the resistivity of plastics; add antioxidants / light stabilizers to improve the weather-ability of the material; add pigments/dyes to change the color of the material, add internal/external lubricants to improve the processing properties of the material, the use of nucleating agents to change the crystalline properties of semi-crystalline plastics to improve their mechanical and optical properties, etc.
