Ingredient: the polymer of ethylene glycol and ethylene oxide
Other Name: carbon wax, PEG
Structural Formula: CH₂(OH)-(CH₂CH₂O)n-CH₂OH
Technical Index:

Properties and Uses:
Polyethylene glycol series products are usually soluble in the water and many kinds of organic solvents, insoluble in the fatty hydrocarbon, benzene and glycol. They don't hydrolyze and deteriorate in quality, and have wide solubility range and excellent compatibility, excellent stability, lubricating property, film-forming property, plasticity and dispersion. They are nonionic polymer with low toxicity and no pungency.

Polyethylene glycol have excellent properties and their molecular weight is adjustable, therefore, they are widely used in many fields such as plastic, rubber, pharmaceutical, food, cosmetic, coating, ink, adhesive, paper making, textile, oil exploration and the process of metal, wood, leather and ceramics, photographic and packing material, etc.

Applications:
Polyethylene glycol are mainly used in two kinds of modes: one mode is that PEG are contained in the final products, for example: used in unguent, ointment, lotion, suppository and tablet in pharmaceutical industry; used in toothpaste, hair cream, deodorant, cleaning cream in cosmetic industry; used in press-polished paper in paper making industry; and used in nylon fibre, celluloid film, adhesive, detergent, flux, varnish and photographic developer, etc. Another mode is that PEG provide lubricating property for many kinds of products, for example: used as shaping lubricant for metals, ceramic tile and porcelain products; used as lubricant in silking, textile fibre, tyre manufacture and medical surgical suture; used as demoulding agent in the formation of latex foam.

PEG200: used as the medium and heat carrier in organic synthesis; as humectant, solubilizer of inorganic salts and viscosity regulator in daily chemical industry; as softening agent and antistatic agent in textile industry, and as wetting agent in paper making and pesticide industry.

PEG400, 600: used as the substrate in medicine and cosmetic; as lubricant and wetting agent in rubber and textile industry. PEG600 is used as wetting agent in wood industry, to improve grinding effect and strengthen the lustre of metal surface when used in electrolyte in metal process.

PEG1000-1500: used as substrate, lubricant and softening agent in pharmaceutical, textile and cosmetic industry; as dispersant to perfect the water dispersibility and flexility of resin in coating industry (the use level is 10-30%); to improve the solvability of dyes and reduce the volatility in ink; also used in stencil paper and stamp pad ink; as well as used in ball pen ink to regulate the viscosity of ink and as dispersant in rubber industry.

PEG2000-3000: used as film-casting agent in metal process; as lubricant and cutting solution in metal wiredrawing, impact extrusion or moulding; as cooling polishing agent and solder; as lubricant in paper making industry.

PEG4000-6000: used as substrate in pharmaceutical and cosmetic industry to regulate the viscosity and melting point; as lubricant and coolant in rubber and metal process industry; as dispersant and emulsifier in pesticide and pigment industry; and as antistatic agent and lubricant in textile industry.

Packing and Storage:
For PEG 200-600, 200kg/iron barrel; for PEG 1000, 10kg/plastic barrel; for PEG 1500-6000, 10kg/plastic barrel or 25kg/woven bag lined with plastic film. Stored in dry, shady and cool place; keep away from fire and prevent them from contacting with heat and oxides.
