Concentrates of dyes and additives
PVC compositions are a thermoplastic material based on polyvinyl chloride, containing plasticizers, heat stabilizers, and other technological additives.
PVC compositions are produced by intensive mixing of the components followed by plasticization of the mixture in an extruder.
The introduction of a plasticizer into a polymer composition makes the product softer, more flexible, and more elastic. The products acquire the ability to work at sub-zero temperatures. As the plasticizer content in the composition increases, the product becomes softer and more ductile.
The introduction of a stabilizer allows the composition to be processed at elevated temperatures, lubricants and flow modifiers reduce the adhesion (adhesion) of the melt to the equipment, impact modifiers increase resistance to loads during operation, fillers increase the viscosity of the melts, and also reduce the cost of the composition.
Finished PVC compositions are processed using various methods – extrusion, rolling, and injection molding.
PVC compounds are widely used in many industries: in the electrical, furniture, construction, food, footwear, automotive, machine-building and nuclear industries. The production of new types of plastics is constantly being developed for the manufacture of various types of cables used in modern power, computer networks and communication systems.
The Realpax company offers the following range of PVC compositions:
- of different hardness (from 50 to 95 Shore hardness)
- varying degrees of color: transparent, natural, colored.
- by release form: granular or powdered.
Our team is ready to select from the available range or produce an individual type of composition, taking into account the characteristics of the customer’s equipment and requirements for the final product.
Thermoplastic elastomer or TEP is a polymer material that has the properties of rubber. The structure of TEP consists of two microscopic phases. The first phase is a soft, easily deformable block, the second is a hard block connecting elastic zones. Thus, its internal characteristics of TEP can change depending on temperature: from an elastic polymer to a polymer liquid.
When TEP is heated above the melting point, the rigid phase melts and allows the polymer to flow into the processing equipment. At lower temperatures, TEP has elastomeric properties and quickly recovers its shape after stretching or compression.
The limiting temperature for the use of TEP is the melting temperature of the plastic phase. The minimum temperature for the use of TEP is well below this limit and is limited by the polymer’s ability to withstand oxidative and chemical degradation, which increases significantly at high temperatures.
TEP can be processed by the methods typical for thermoplastics, such as casting, or by calendering and rolling, which are typical for elastomers.
When processed, thermoplastic elastomers do not undergo the vulcanization stage like rubber (a technological process of interaction of a material with a vulcanizing agent, during which rubber molecules are crosslinked into a single spatial network). TEP can be recycled many times.
The scope of application of TEP is very wide. The performance characteristics of TEP allow this material to be used in most industries. The main and most popular properties of thermoplastic elastomers are elasticity and plasticity. Thanks to these and other properties, TEP is successfully used in the shoe industry.
TEP is non-toxic, so its use is possible in the production of household appliances, cutlery, children’s toys, pacifiers, and toothbrushes.
TEP is a dielectric, so it is excellent for making cords, cables, control panels, and elastic telephone gaskets. TEP is a material with high resistance to oils that meets the temperature requirements for a number of technical applications, such as seals under the hood of a car engine, protective covers, and hoses. TEP is resistant to environmental influences, is not afraid of moisture, UV radiation, acids, and alkalis, so it is used in the production of building materials: window and door seals, fasteners, cladding, and hoses.
The Realpaks company offers the following range of thermoplastic elastomers: of different hardness (from 50 to 95 Shore hardness) of different degrees of color: transparent, natural, colored. Our team is ready to select from the existing range or produce an individual composition of TEP taking into account the features of the customer’s equipment and requirements for the final product.
