Polypropylene (PP)
PP materials are universally standard plastics with well-balanced properties that ensure excellent chemical resistance, high purity, low water absorption and good electrical insulation properties. In addition, polypropylene material is light, conductive and weldable.
Polyethylene (PE)
PE polymers are semi-crystalline thermoplastics characterized by high toughness and excellent chemical resistance. However, unlike other plastics, polyethylene plastic has lower mechanical strength and temperature tolerance.Üksikute polüetüleenitüüpide molekulmass võib olla väga erinev, mis omakorda mõjutab otseselt üksikute tüüpide suhtelisi füüsikalisi omadusi. Lisaks nendele omadustele PE pakub veel: head löögitugevust madalatel temperatuuridel, hea vibratsioonisummutus, suurepärane keemiline vastupidavus jne.
Polyvinyl chloride (PVC)
It is difficult to compare the performance of PVC. It is durable, light, strong and fire resistant, with excellent insulating properties and low permeability. By using additives in the manufacturing process, properties such as strength, stiffness, weather resistance, color and transparency can be tailored to specific needs
Unplasticized polyvinyl chloride (PVC-U)
The full name of this product is unplasticized polyvinyl chloride. Since there is no plasticizer added to this plastic, it means that this product is much more rigid than PVC material, it is hard and does not bend at all. It does not contain phthalates or BPA, which makes this plastic much safer than many other similar plastics. Main uses: window frames, water pipes, sewer pipes, drainage systems.
Chlorinated polyvinyl chloride (PVC-C)
This corrosion-resistant system offers durability and maximum safety in aggressive applications. PVC-C is used wherever aggressive substances such as lactic acids or acids are transported at high temperatures, e.g. in the chemical, paper and pulp industry, metalworking or microelectronics production.
PVC-C pipes can be used at operating temperatures between 0 °C and 80 °C and are suitable for higher ambient temperatures.
Polyvinylidene fluoride (PVDF)
PVDF plastic is characterized by excellent chemical resistance without sharing the disadvantages of other fluoroplastics, such as low mechanical values or processing difficulties. The melting point of PVDF is 171 °C.
Because polymer PVDF has very good thermal and chemical resistance, it is commonly used in the construction of chemical plants or as a lining for PVDF pipes or external components. It can also be used for gaskets, membranes and packaging films.
Polypropylene homopolymer (PP-H)
PP-H polypropylene is characterized by high mechanical and tensile strength, but does not withstand sharp impacts. PP-H is resistant to stress cracking and is easy to weld and vacuum form. At sub-zero temperatures, it can become brittle. PP-H has very good chemical properties. The operating temperature range of polypropylene is 0 °C to +100 °C.
High density polyethylene (HDPE)
High-density polyethylene, commonly abbreviated to HDPE, is a thermoplastic polymer that is sometimes called polyethylene when used for HDPE pipes. It is one of the most versatile plastics with outstanding tensile strength and a high strength-to-density ratio. It is used in a variety of packaging and commercial applications.
Ethylene chlorotrifluoroethylene (ECTFE)
ECTFE is stronger, stiffer and more dimensionally stable than many other fluoropolymer materials. It has excellent electrical properties, low coefficient of thermal expansion and low moisture absorption. ECTFE has exceptionally smooth surfaces compared to other fluoropolymers, making it an ideal choice for many high-purity applications in the pharmaceutical and semiconductor industries.
Main applications: tank, vessel and reactor linings, agitators, centrifuges, pipe systems and filters.
