EVA car interior sheet extruder

Car Interior Sheet Extruder
Plastic sheet refers to heating and melting plastic raw materials (particles) in a plastic extruder or plastic calender and then extruding or calendering them into a thickness of... Plastic rolls left and right. The thickness of the plate is greater than (the thickest can be reached)[].
This type of material mainly includes etc.
Features: Good heat resistance, good chemical corrosion resistance, high mechanical strength, reliable electrical insulation performance, good hygiene, and excellent chemical stability.

Composition
Synthetic resin
Synthetic resin is the main component of plastics, and its content in plastics is generally %~%. Due to the large content and the properties of the resin often determine the properties of the plastic, people often regard the resin as a synonym for plastic. For example, polyvinyl chloride resin and polyvinyl chloride plastic, phenolic resin and phenolic plastic are confused. In fact, resin and plastic are two different concepts. Resin is an unprocessed raw polymer that is used not only to make plastics but also as a raw material for coatings, adhesives and synthetic fibers. Except for a very small part of plastics that contain % resin, most plastics need to add other substances in addition to the main component resin. Filler
Car interior sheet extruder
Filler is also called filler, which can improve the strength and heat resistance of plastics and reduce costs. For example, adding wood powder to phenolic resin can greatly reduce the cost, making phenolic plastic one of the cheapest plastics, and it can also significantly improve the mechanical strength. Fillers can be divided into organic fillers and inorganic fillers. The former such as wood powder, rags, paper and various fabric fibers, etc. The latter such as glass fiber, diatomaceous earth, asbestos, carbon black, etc.

Plasticizer
Plasticizers can increase the plasticity and softness of plastics, reduce brittleness, and make plastics easy to process and shape. Plasticizers are generally non-toxic, odorless, light-resistant, and thermally stable high-boiling organic compounds that are miscible with resins. The most commonly used plasticizers are phthalates. For example, when producing polyvinyl chloride plastic, if more plasticizer is added, soft polyvinyl chloride plastic can be obtained. If no or less plasticizer (amount %) is added, hard polyvinyl chloride plastic can be obtained.

Stabilizer
In order to prevent the synthetic resin from decomposing and being damaged by light and heat during processing and use to extend the service life, stabilizers should be added to the plastic. . Commonly used ones include stearate, epoxy resin, etc.

Colorants
Colorants can make plastics have various bright and beautiful colors. Organic dyes and inorganic pigments are commonly used as colorants. Lubricant
The function of lubricant is to prevent the plastic from sticking to the metal mold during molding and to make the surface of the plastic smooth and beautiful. Commonly used lubricants include stearic acid and its calcium and magnesium salts.
In addition to the above-mentioned additives, flame retardants, foaming agents, antistatic agents, etc. can also be added to plastics to meet different usage requirements.
