Question:

Is the polyethylene plate pvc board?

Polyethylene board is not pvc board? If not, then what is the difference between the two? Thank you

Answer:

Polyethylene sheet is not PVC board. Polyethylene board, also known as low-pressure high-density polyethylene, HDPE board, PE board, HDPE rod. Is a high degree of crystallinity, non-polar thermoplastic resin. The appearance of the original HDPE was milky white, in a slight cross-section was a certain degree of translucent. Polyethylene sheet (HDPE board) melting point of about 130 ℃, the relative density of 0.941 ~ 0.960. It has good heat resistance and cold resistance, chemical stability, but also has a high rigidity and toughness, good mechanical strength. Dielectric properties, resistance to environmental stress cracking is also better. Melting temperature of 220 ~ 260C. For larger materials, the proposed melting temperature range between 200 ~ 250C. PVC board is PVC as raw material made of cross-section for the honeycomb mesh structure of the plate. Is a vacuum plastic film, used for all kinds of panel surface packaging, it is also known as decorative film, with film, used in building materials, packaging, medicine and many other industries. PVC board in the building materials industry accounted for the largest proportion of 60%, followed by the packaging industry, there are several other small-scale application of the industry. According to the degree of soft and hard can be divided into soft PVC and hard PVC. According to the production process can be divided into PVC crust foam board and PVC free foam board.
First, polyethylene, referred to as PE, ethylene is produced by polymerization of a thermoplastic resin. Polyethylene odorless, non-toxic, feel like wax, with excellent low temperature performance (minimum temperature up to -70 ~ -100 ℃), good chemical stability, the ability of most of the acid-base erosion (intolerant with oxidative properties Acid), which is insoluble in general solvent at room temperature, has low water absorption, and has excellent electrical insulation performance. However, polyethylene is very sensitive to environmental stress (chemical and mechanical action) and has poor heat aging resistance.
