What raw material (HDPE) made of plastic bags, high transparency, good sense of light master?

Answer:

The plastic we usually use is not a pure substance. It is made up of many materials. The polymer (or resin) is the main component of plastic, in addition, in order to improve the performance of plastics, but also add various auxiliary materials in the polymer, such as filler, plasticizer, stabilizer, lubricant, coloring agent, can become the good performance of plastic.

Synthetic resin is the most important component of plastics, and its content in plastics is generally between 40% and 100%. Because of the large amount and the nature of the resin, which often determines the nature of plastics, people often think of resin as a synonym for plastics. For example, PVC resin is mixed with PVC plastic, phenolic resin and phenolic plastics. In fact, resin and plastics are two different concepts. Resin is an unprocessed primitive polymer that is used not only in plastics but also as raw material for paints, adhesives and synthetic fibers. In addition to a very small number of plastic containing 100% of the resin, the vast majority of plastic, in addition to the main component resin, but also need to add other substances

Fillers, also called fillers, 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, and make phenolic plastic one of the cheapest plastics, and can also significantly improve the mechanical strength. Packing can be divided into two kinds of organic fillers and inorganic filler, the former such as wood powder, rags, paper and all kinds of fabric, the latter such as glass fiber, diatomite, asbestos, carbon black.

Plasticizers can increase plasticity and softness of plastics, reduce brittleness, and make plastics easy to process and shape. Plasticizers are generally miscible with resins, nontoxic, odorless, and highly volatile organic compounds that are stable in light and heat. The most commonly used are phthalate two formic acid esters. For example, the production of PVC plastic, if you add more plasticizers, you can get soft PVC plastic, if not added or less plasticizer (dosage <10%), then hard PVC plastic.
