HDPE sheets

HDPE provides a powerful aid in creating durable, attractive structures, as well as in glazing buildings, performing roofing works, fabricating exterior wall cladding, and fabricating various types of fencing. For roof waterproofing, protection of block, brick, concrete buildings from moisture, manufacture of composite panels, 6mm thick low pressure polyethylene panels are perfect.

All types of HDPE are rigid and rigid plastics. However, the physico-mechanical properties of HDPE and its price are directly dependent on its production method. Common processing methods are extrusion and molding. Extruded HDPE sheets have low ductility and flexibility, but are highly resistant to tearing loads. The HDPE board produced by the molding process has stronger mechanical strength and ductility. It has a more uniform structure with good ductility and crack resistance.

The high-density polyethylene produced by Henan OKAY is made of high-quality pure polyethylene, does not contain recycled material additives, and meets the requirements of industry standards. It has the necessary certificates and test reports. HDPE sheet is resistant to cracking, tearing and shrinkage. It will not crack, rot or corrode, and will not allow steam and moisture to pass through. It can be used in contact with food due to its biological inertness. Henan OKAY wholesales and retails HDPE, and can produce HDPE sheets of various shades according to customer requirements.

HDPE is a durable waterproof material that resists chemicals and UV rays. It has high moisture resistance, does not lose elasticity in heat and frost, and is a good electrical insulator. Due to its affordable cost and excellent properties, black polyethylene is widely used in various industries. Polyethylene sheets are easily welded with hot tools, can be bent and glued. It is ideal for all types of machining and can cut any shape profile from this material.

Advantage:
Polyethylene respectively has higher frost resistance (up to -60 degrees Celsius) and good impact resistance at subzero temperatures.
The upper limit of operating temperature is +70 degrees. C. Polypropylene has higher heat resistance (up to +90 degrees Celsius).
Polyethylene is a more elastic and less brittle polymer. And polyethylene sheet has higher flexibility and density.
The surface of polyethylene sheet is less resistant to contamination than polypropylene. PP sheet has a harder (harder) surface.
Like polypropylene, sheet polyethylene has a high chemical composition. Durability. Polyethylene is moisture impermeable and resistant to fuels and lubricants, alcohol, oils and fats. It does not react with acid, alkali and salt solution, and is insoluble in organic solvents.

In terms of physical and mechanical properties, polyethylene sheets are similar to polypropylene sheets because they belong to the same class of polyolefins. But there are still significant differences, for example, polyethylene sheets have a higher density of 0.96 g/cm3, they are stiffer, and they have improved chemical resistance to certain compounds that polypropylene is not resistant to. In addition, polyethylene sheets are more frost resistant, and thanks to the presence of UV stabilizers, they resist solar radiation, do not fade, and do not collapse. PE sheets are perfect for almost any process, they can be sawn, drilled, milled, bent, hand welded and butt welded, as well as shaped, cut and glued together.

A characteristic of HDPE is the sound it makes when hit. This attribute is often used to identify products “by the naked eye” in order to quickly distinguish them from products made from other types of plastics. HDPE is easily processed by a variety of methods, allowing the production of a wide variety of products. This material is ideal for gas, chemical, and thermal welding. Thereby, industrial and household products can be produced by extrusion methods, pressure casting methods, rotational molding methods. HDPE has been widely used in industrial fields where the high strength properties of the polymer are important. It is also needed in the construction industry, in the production of consumer goods.
