Stearic Acid 1860 Lubricant High-Quality Lubrication for Plastics

Characteristics

Good lubrication performance: Stearic acid 1860 has a long carbon chain in the molecule. During the plastic processing, it can form an isolation layer between polymer molecules, reduce the friction between molecules, and effectively improve the fluidity of plastics.

It can reduce the adhesion of plastic melt on the surface of processing equipment (such as screws and molds), reduce energy consumption, improve processing efficiency, and make the surface of plastic products smoother and flatter.

Good compatibility with plastics: It can be well compatible with a variety of plastics such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), etc., and is evenly dispersed in the plastic matrix. It will not affect the basic properties of plastics, such as mechanical properties and thermal properties, and can continue to play its lubricating role.

High thermal stability: Within the general plastic processing temperature range (usually 160℃ - 220℃), stearic acid 1860 has good thermal stability, is not easy to decompose or volatilize, and can stably play a lubricating function during the processing process to ensure the smooth progress of plastic processing.

Auxiliary demoulding effect: As a lubricant, stearic acid 1860 also has certain auxiliary demoulding properties. It can reduce the adhesion between plastic products and molds, make products easier to be released from molds, reduce damage to products during demoulding, and improve the qualified rate of products.

Application field

PVC processing: In the production of PVC pipes, profiles, films and other products, stearic acid 1860 is often used as an internal lubricant. It can promote the plasticization of PVC resin, reduce melt viscosity, improve processing performance, and improve the surface quality and dimensional stability of products.

PE and PP processing: For the injection molding, blow molding and other processing processes of polyethylene and polypropylene, stearic acid 1860 can be added as a lubricant to improve the fluidity and demoulding performance of plastics and reduce surface defects of products, such as flow marks and shrinkage marks.

Other plastic processing: It is also suitable for the processing of other plastics such as polystyrene (PS) and ABS, and can play a positive role in improving plastic processing performance and product quality.

Precautions

Addition amount control: Although stearic acid 1860 has many benefits for plastic processing, the addition amount needs to be strictly controlled. Excessive addition may lead to a decrease in the mechanical properties of plastic products, such as reduced tensile strength and impact strength, and may also affect the thermal stability and surface gloss of the products.

Generally speaking, the addition amount is between 0.1% and 1%, depending on the type of plastic and processing requirements.

Storage conditions: It should be stored in a cool, dry, well-ventilated warehouse to avoid moisture and direct sunlight. Stearic acid 1860 has strong hygroscopicity, which may affect its performance after being exposed to moisture, and may oxidize and deteriorate in high temperature environments, reducing the lubrication effect.

Interaction with other additives: In actual applications, stearic acid 1860 is usually used in combination with other additives such as stabilizers, plasticizers, antioxidants, etc.

It is necessary to pay attention to the interaction between these additives. Some additives may react chemically with stearic acid 1860, affecting its lubrication performance or the effects of other additives, so sufficient testing and evaluation are required before use.

Safety protection: When handling stearic acid 1860, wear appropriate protective equipment such as gloves, masks, etc. to avoid direct contact with the skin and inhalation of dust. Although it is generally considered to be of low toxicity, long-term contact or inhalation may have certain effects on human health.
