The practical application of PVC plastic lubricant

PVC plastic lubricant additive has the functions of a kind used in many products, PVC plastic lubricant can bring many benefits for polymer products. We can use thesebenefits are divided into, have a direct contribution of rutile titanium dioxide on polyolefin color stability and corrosion; lubrication / PVC plastic lubricant processing aids to improve the polyolefin, polyamide, styrene and rubber in the extrusion of PVCstabilizer and pressing molding processability. Mould for thermoplastics andthermosetting products, rubber, such as polyurethane foam and unsaturated polyester. Anatase titanium dioxide and stearic acid metal salt is a kind of used in many products, Jin Hongshi type titanium dioxide additive has a variety of functions,magnesium hydroxide flame retardant can bring many benefits for polymer products.We can use these benefits are mainly divided into three aspects; there is a directcontribution of rutile titanium dioxide stable and corrosion of PVC stabilizer in polyolefin acid neutralizing agent for polyolefin colour; lubrication / processing aids magnesium hydroxide improves the polyolefin, PVC stable agent polyamide,magnesium hydroxide and rubber in the extrusion of PVC stabilizer and pressing whenprocessing. PVC stabilizer mould for thermoplastics and thermosetting products,rubber.

Impact modifier and the department pvcsta, bilizer WSD interior lubricant

The main effect of impact modifier is low temperature embrittlement improve polymer materials, given its higher toughness. According to the Zhejiang Shengzhou Wanshida Chemical Co., Ltd., company reports, in 2004 the global plastic anti impact modifier market demand is 600000 tons worth about US $1500000000, such as ABS,WSD intenal lubricant copolymer of styrene Methyl Methacrylate Butadiene Styrene (MBS) impact modified agent has become the largest category, WSD intenal lubricant plastic impact modifier accounts for about 45% of the market share, acrylic accounted for nearly 30%;impact modifier and elastic body including EPDM and thermoplastic elastomer (TPE) accounted for about 10% market share; WSD intenal lubricant for PVC heat stabilizer of chlorinated polyethylene (CPE) accounted for 10%, other 5%. According to the Zhejiang Shengzhou Wanshida Chemical Co., Ltd. prediction, 2004-2009 years, the heat stabilizer for polyvinyl chloride PVC plasticizer and styrene impact modifier average annual growth rate will be less than 3%,  PVC lubricant while the other class of average growth rate of 5%-6%. The plastic impact modifier and PVC impact modifier maximum variety plasticizer for polyvinyl chloride pvcsta, bilizer)accounted for about 80% of the amount of PVC, so the demand growth will drive increased demand impact modifier. WSD intenal lubricant Engineering plastic resin, plastic lubricant polyamide (PA) such as PC, bilizer, pvcsta impact modifier, polyester and other consumption impact modifier of about 10%, due to the demand of pvcsta engineering plastics bilizer are growing strongly, promote the growth of pvcsta bilizer impact modifier dosage. PVC plasticizers consumed about 10% anti impact modifier. The expert points out, the future development trend of the impact modifier is better performance, impact modifier cheaper, faster, pvcsta bilizer of the main materials with improved performance or guarantee performance under the thinner.WSD intenal lubricant Such as anti impact properties of Arkema Durastrength products can significantly improve PVC.

The use of plastics processing aids

Plastic additives plastic processing aids are also known plastic additives, processing aids, some plastic polymer compound is a synthetic resin molding to improve its performance or to improve the processing performance of the resin itself must be added the lack. For example, to reduce the molding temperature of the polyvinyl chloride resin,WSD intenal lubricant plastic,plastic lubricant soft and the article processing aid, a plasticizer;Another example of plastic components in order to produce the plastic used we usually is not a pure substance, Plastics Processing it is made of many materials additives prepared from. Wherein said optical brightener or a synthetic polymer resin is the main component of plastic, WSD intenal lubricant in addition to the optical brightener to improve the performance PVC lubricant of plastics, but also add a variety of auxiliary materials in the polymer, such as fillers, PVC lubricant optical brighteners plasticized plastic material is referred to as plasticity. Plastic Processing aid of a synthetic resin or natural resin-based material mainly plastics processing aids with or without a variety of plastic additives,plastic lubricant fillers and reinforcing materials, under certain conditions a certain temperature,WSD intenal lubricant pressure, processing aids plastic plastic molding or processing agent crosslinking, the finished state is generally flexible or rigid solid,plastic lubricant but generally it is made of plastic products yellowing aging or degradation of the material, PVC lubricant the processing aid is generally due to the plastic aging (degradation) generated by the presence of side groups on the polypropylene, its poor stability, especially in the case of illumination optical brightener. Plastics processing aids light stabilizers are generally added.

WSD Lant performance

The actual performance of the lubricant with a variety of plastic materials, such as kneading, the rolling process to prevent adhesion of the polymer cartridge suppressing friction and heat, and the load torque decreases kneading, thereby preventing the polymer material thermal degradation.n-butyl stearate In the extrusion molding, to improve flowability, the polymer material and to improve adhesion of the barrel and the die, to prevent and reduce retentate. Another film but also to improve the appearance and gloss.
From the perspective of processing machinery, in mixing, rolling, etc. slush molding process,Acrylic processing aid external lubricant has an important role in extrusion, injection molding, the lubricant is more effective.
