HDPE high-density polyethylene

High-density polyethylene (HDPE) is a granular or white powder plastic material that is non-toxic and tasteless. It has a crystallinity of 80% to 90%, a softening point of 125 to 135°C, and a service temperature of up to 100°C. Compared to low-density polyethylene, HDPE has better hardness, tensile strength, and creep, as well as wear resistance, electrical insulation, toughness, and cold resistance. It also has good chemical stability and is insoluble in any organic solvent at room temperature. HDPE is highly resistant to corrosion from acids, alkalis, and various salts. HDPE film has low permeability to water vapor and air and low water absorption, which means it’s less susceptible to damage from humidity. However, it has poor aging resistance, and its environmental stress cracking resistance is not as good as low-density polyethylene. To improve its deficiency, antioxidants and ultraviolet absorbers should be added to the resin. HDPE film also has a low heat distortion temperature under stress, so it should be applied with care.

High-density polyethylene (HDPE) resins are versatile and can be used to manufacture plastic products through a variety of processes such as injection moulding, extrusion, blow moulding, and rotational moulding. Injection moulding can be used to produce a range of products, including containers, industrial accessories, medical supplies, toys, shells, bottle stoppers, and shields. Blow moulding is suitable for creating different types of hollow containers and ultra-thin films. Extrusion moulding is used to form tubing, stretch tape, strapping, monofilament, and wire and cable sheathing. HDPE can also be used to create architectural decorative panels, shutters, synthetic wood, synthetic paper, synthetic film, and calcium-plastic products.

LDPE low-density polyethylene

Low-density polyethylene (LDPE), also referred to as high-pressure polyethylene, is the least dense type of polyethylene resin. It appears milky white, is odorless, tasteless, and non-toxic. It is a waxy particle with a dull surface. LDPE has a density ranging from 0.91g/cm3 to 0.93g/cm3 and exhibits excellent flexibility, extensibility, electrical insulation, transparency, processability, and air permeability. Additionally, LDPE has good chemical stability, alkali resistance, and resistance to most organic solvents.

The scope of application of low-density polyethylene:

Low-density polyethylene, or LDPE, has a wide range of applications, including food packaging for products like seasonings, pastries, sugar, candied fruit, biscuits, milk powder, tea, and fish floss, as well as pharmaceutical packaging for tablets and powders. It is also used for packaging fiber products such as shirts, clothing, and knitted cotton and chemical fiber products, as well as for packaging washing powder, detergent, cosmetics, and other daily chemical products. However, due to the poor mechanical properties of single-layer PE film, it is typically used as the inner layer of composite packaging bags, serving as the heat-sealing substrate for multi-layer composite films.

VAE Ethylene vinyl acetate

Ethylene vinyl acetate, in short VAE, which is also called redispersible powder(RDP) is widely used in the construction field. It can be used in the cement mortar, wall putty, EIFS mortar, inner wall mortar, tile bonding mortar and tile seam filling. The extraordinary bonding ability make it a very outstanding bonding additive in the construction. And also improves the coating and spreading rate of the mortar or putty. Also anti cracking, highly improves the strength for the structures.

HPMC Hydroxypropyl Methyl cellulose

According to the dissolving property, the HPMC can be mainly divided into 2 types. The instant dissolving type, which is widely applied in the detergent industry. Such as shampoo, liquid soap, dish washing detergent, tooth paste, cloth washing detergents, painting, capsule, etc. This type of HPMC can be dissolved into room temperature water, and with high permeability. It can act as thickener, excipient, emulsifier, film-forming agent and dispersant.

These applications requires a very high standard type of HPMC, thus it shall have the following features:

Shall be dissolvable in room temperature water.
The solution shall be of high permeability.
Gain viscosity within 30-60 minutes.
No stains after storage of several weeks.

The other type is hot dissolving HPMC. This type only have quick dissolving effect under the condition of hot water above 60 ℃. This type of HPMC is mainly used in the construction, ceramic industry, textile industry etc. It can be used as thickener, water retention agent, prolonging the open time, ensures the mortar or wall putty to be anti-drooping, anti-cracking and improves the work-ability. The function of HPMC is very distinct.
