Non Toxic LDPE HDPE Polyethylene Profiles For Snow Plow

Pe Profile Snow Plow Accessories Low Pressure At -70℃ Is Still Flexible

Dectription

Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (minimum operating temperature can reach -100~-70°C), good chemical stability, and can resist most acid and alkali erosion (not resistant to oxidation nature acid). It is insoluble in common solvents at room temperature, with low water absorption and excellent electrical insulation.

Polyethylene Thermoplastic Characteristics

Polyethylene (PE) is the most widely used thermoplastic polymer for fabricated parts and components. It is available in a variety of grades and formulations to suit different needs. In general, polyethylenes offer excellent chemical and impact resistance, electrical properties and low coefficient of friction. It is considered a dielectric material. In addition, polyethylenes are lightweight, easily processed and offer near-zero moisture absorption.

Classification

Polyethylene is divided into high density polyethylene (HDPE), low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) according to the polymerization method, molecular weight and chain structure.

LDPE

Properties: tasteless, odorless, non-toxic, dull surface, milky white waxy particles, density about 0.920 g/cm3, melting point 130℃～145℃. Insoluble in water, slightly soluble in hydrocarbons, etc. It can withstand the erosion of most acids and alkalis, has low water absorption, can still maintain flexibility at low temperatures, and has high electrical insulation.

Production process: There are mainly two kinds of high-pressure tube method and kettle method.

Uses: Injection molding, extrusion molding, blow molding and other processing methods can be used. Mainly used as agricultural film, industrial packaging film, pharmaceutical and food packaging film, mechanical parts, daily necessities, building materials, wire, cable insulation, coating and synthetic paper, etc.

HDPE

Properties: natural color, cylindrical or oblate particles, smooth particles, particle size should be 2 mm ~ 5 mm in any direction, no mechanical impurities, thermoplastic. The powder is white powder, and the qualified product is allowed to have a slight yellow color. It is insoluble in common solvents at room temperature, but can swell in aliphatic hydrocarbons, aromatic hydrocarbons and halogenated hydrocarbons when exposed to it for a long time, and is slightly soluble in toluene and acetic acid at temperatures above 70°C. Oxidation occurs when heated in air and under the influence of sunlight. Resistant to most acid and alkali erosion. It has low water absorption, can still maintain softness at low temperature, and has high electrical insulation.

Production process: two production processes of gas phase method and slurry method are adopted.

Characteristics of these include:
