Evaluation of stretch film production auxiliaries

In the stretch film processing production, a variety of excellent performance of the stretch film additives in improving product quality plays an important role.
As the world's leading manufacturer of flame retardants and the largest manufacturer of stretch film additives, the United States Branch of the company in the rubber and plastics exhibition launched a polymer modifier, antioxidant, heat stabilizer, light stabilizer , Lubricants and flame retardants and a series of stretch film processing aids. Among them, Mark OBS? Series of organic stabilizer, which does not contain heavy metals, represents the latest research results of polyvinyl chloride heat stabilizer. Non-toxic, colorless, excellent thermal stability, can replace lead salt, calcium zinc or organic tin and other traditional PVC stabilizer for pipe, profiles, sheet and other PVC molding products can also be used directly with Food contact with the hard PVC products.

In the stretch film antistatic agent, the Japanese Sanyo Chemical Industry Co., Ltd. introduced Pelestat? Series of permanent antistatic agent, Switzerland Ciba Specialty Chemicals Co., Ltd. launched Irgastat? Series of permanent antistatic agent. These two antistatic agents are in the form of granules and can be added on demand as needed during extrusion, blow molding and injection molding without the need for pre-mixing granulation. The permanent antistatic agent can be incorporated into the polymer matrix during the melting process to form a permanent electrostatic dissipative network in the product. The surface resistance of the product can be stabilized at 10 (8th order) to 10 (11 th power) / M2 level. Since the permanent antistatic agent is non-migratory, it is not corrosive or contaminating, and the product retains its original color and transparency. In the injection molded products, the permanent antistatic agent mainly concentrated in the surface layer, and in the mold flow direction preferred orientation, the mechanical properties of the base resin has no effect. Even if the product is wiped or washed, the permanent antistatic agent will remain in the surface, and the low molecular antistatic agent is easily removed by wiping or washing. This type of antistatic agent is the automotive, home appliance industry to develop the next generation of non-stick ash products required for the key additives.
BASF has introduced a new generation of plasticizers, Palatinol® 10 and Hexamoll® DINCH, which replace DOP and DIDP in stretch film plasticizers. Palatinol 10 has outstanding resistance to outdoor and weather applications. The effect, no smell and better processing performance, and most of the auxiliary plasticizers, stabilizers and additives compatible. Hexamoll® DINCH is BASF's innovative plasticizer for sensitive applications that fully meets EU chemical regulatory requirements and is recognized by many of the world's leading authorities for the most stringent safety and quality requirements Quality PVC products, such as medical equipment, toys, food containers, sports and leisure products. Hexamoll DINCH has low viscosity, low volatility, low mobility and no odor, and has good compatibility with PVC.
Stretch film
In the stretch film processing aids, Japan's Daikin Industries Co., Ltd. introduced a special treatment of PTFE powder prepared Polyflon series of anti-dripping agent and Lubron series of wear-resistant lubricants. In the project stretch film flame retardant products, adding 0.1% to 0.5% of the Polyflon? Anti-dripping agent, can help to prevent flame retardant and to prevent PC, ABS and PBT and other stretch film melting dripping effect. And in a variety of stretch film, rubber material by adding 1% to 5% Lubron? Wear-resistant lubricant, can significantly reduce the material surface friction coefficient, enhance weather resistance, improve wear resistance, scratch resistance, non-stick And stain resistance.
At this International Rubber and Plastic Exhibition, the Beijing Chemical Industry Research Institute launched the self-developed Napu series of ultra-fine vulcanized powder rubber (UFPR), its particle size is less than 100 nm, has been in the tensile film toughening modification, Friction materials and the preparation of vulcanized thermoplastic elastomers and other aspects are widely used. Napu series of product technology has applied for 38 domestic and foreign patents, and has built a thousand-ton production plant. Napu series includes ultra-fine vulcanized powder styrene-butadiene rubber, ultra-fine vulcanized powder carboxylated styrene-butadiene rubber, ultra-fine vulcanized powder acrylic rubber, ultra-fine vulcanized powder and other rubber.
Through the one-year international rubber and plastics exhibition, we feel the pulse of the stretch film market. In the market globalization, increasingly stringent environmental requirements and rapid oil prices in front of the stretch film industry how to deal with? Stretch film additives has become a product development must consider an important factor.
