Product Features
Excellent Plasticizing Performance: It can effectively improve the fluidity during the plastic processing, enhance the plasticity of plastic materials, making plastic products softer and easier to be processed and formed.
Outstanding Cold Resistance: It can maintain good performance in low - temperature environments. Products containing it still have good flexibility and elasticity under cold conditions, and are not prone to hardening and embrittlement.
Superior Oil Resistance: It can endow synthetic rubber and other products with good oil - resistant properties. When in contact with oil substances, it can maintain its own physical and chemical stability.
Certain Biocompatibility: In some application scenarios, it has good compatibility with biological tissues or substances, and can be used in some biology - related fields.
Low Toxicity: It is generally considered non - toxic and can be used in fields such as packaging materials that come into contact with food.
Application Scope
Plastics industry: It is a plasticizer for plastics such as polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), acrylonitrile - butadiene - styrene copolymer (ABS), etc., which can endow plastics with good flexibility and low - temperature performance.


Rubber industry: As a cold - resistant plasticizer for synthetic rubbers, it can improve the low - temperature elasticity and flexibility of rubber products, such as nitrile - butadiene rubber and neoprene products.


Food packaging: Due to its non - toxicity, it can be used in packaging materials that come into contact with food, such as film - coated capsules, beads, and granules.

Spice industry: It is used to formulate spices such as fruit - flavored essences, adding specific scents to products.

Medical field: It can be used in medical devices and pharmaceutical applications. For example, it can be used as a plasticizer in film - coated capsules.

Cosmetics industry
It is used as a skin emollient and film - forming agent. It can form a uniform film on the skin surface, reducing the loss of skin moisture, increasing the softness and smoothness of the skin, and enhancing the effectiveness and texture of cosmetics.
Lubricant It can be used as a lubricant in shaving lotions. It reduces the friction between the blade and the skin during shaving, making the shaving process smoother and minimizing skin irritation and discomfort.
Propellant Fuel It can serve as the propellant fuel for the desensitizer in torpedo unit components, providing power for the propulsion of torpedoes.

Other aspects: It can also be used as a gas chromatography stationary liquid, pigment dispersant, engine lubricant, antifreeze, and is applicable in fields such as organic synthesis and cable manufacturing.
