As the world’s second largest general-purpose synthetic resin material, PVC has become one of the most widely used plastics due to its excellent flame retardancy, abrasion resistance, chemical corrosion resistance, comprehensive mechanical properties, product transparency, electrical insulation and easier processing, etc. PVC can be divided into rigid PVC and soft PVC.
Rigid PVC:
Rigid PVC is also known as UPVC, can also be referred to as PVC-U type products, hard PVC does not contain softeners, so flexible, easy to form, not easy to brittle, non-toxic and non-polluting, preservation of a long time, so it has a great value of the development and application. Generally it will be used in the pipeline industry, water supply and drainage, flame retardant electric cable casing, electrical appliances in the shape of flame retardant shells, sockets, profiles, plastics, and some of the bumpers and wings and so on.
Soft PVC:
Soft polyvinyl chloride is a kind of general-purpose plastics, due to which contains softener will be very easy to become brittle, and not easy to save, so its scope of use is somewhat limited, generally common soft PVC will be used for flooring, ceilings, leather surfaces, electrical insulation, door sealing materials, toys and so on.
As soft PVC will become hard and brittle after long time use, lose elasticity and not resistant to aging, so when soft PVC products are processed, PVC particles are usually modified to improve the processing performance and surface performance of PVC, so as to improve the service life of soft PVC products.
Plastic Modification Case: Improvement of Surface Abrasion Resistance of Soft PVC Refrigerator Seals
Refrigerator door seals are commonly made of modified PVC type sealing tape, whose tape is produced from modified PVC granules through plastic extruders. Soft PVC refrigerator door seals have good elasticity and sealing, but with the passage of time, this material will be aged, hardened, scratched or even cracked.
Some customers feedback that by adding LYSI-100A and modifying the soft PVC material, the surface abrasion resistance of the products can be obviously improved, which prolongs the service life of the door seals and provides great help to enhance the competitiveness of the products.
SILIKE Silicone powder ( Siloxane powder ) LYSI-100A is a powder formulation which contains 55% UHMW Siloxane polymer dispersed in Silica. It is particularly developed for Polyolefin masterbatches/filler masterbatches to improve the dispersion property by better infiltrate in fillers.
SILIKE Silicone powder ( Siloxane powder ) LYSI-100A, as a processing aid, is suitable for use in a variety of thermoplastic formulations such as PVC compounds, engineering compounds, pipes, plastic/filler masterbatch, halogen-free flame retardant wire and cable compounds.
Adding SILIKE Silicone powder ( Siloxane powder ) LYSI-100A to soft PVC at 0.2%~1% can bring the following benefits:
Enhancing melt Processing.
Better mould filling and release properties.
Reduced extruder torque.
Improved processing efficiency.
Adding SILIKE Silicone powder ( Siloxane powder ) LYSI-100A to soft PVC at 2~5% can bring the following benefits:
Improved surface properties.
Reduced coefficient of friction.
Improved wear and scratch resistance.
Gives products a smooth surface feel.
SILIKE Silicone powder LYSI-100A has a very rich application, at the same time in the application are very good results, LYSI-100A typical applications include:
1.For PVC,PA, PC, PPS high temperature engineering plastics, can improve the flow of the resin and processing properties, promote the crystallization of PA, improve the surface smoothness and impact strength.
2.For cable compounds, obvious improve processing properties and surface finish.
3.For PVCfilm/sheet to improve surface smooth and processing properties.
4.For PVC shoe’s sole , improve abrasion resistance.
