Materials Table:

Code	Max. temperature, °C	Description
U-PVC	60°	Unplasticized polyvinyl chloride. Widely used in the chemical and pharmaceutical industries, water treatment, for the manufacture of housings, as well as lining of baths in galvanic technologies.
PE 100	60°	PE-100 sheet polyethylene is a type of polyethylene with high technical characteristics and a wide range of applications.
PP-H 100	100°	Polypropylene is a material that is widely used in various industrial applications, including chemical engineering, tank manufacturing, pipelines and fittings. It is characterized by high chemical resistance, good mechanical properties and the ability to withstand high temperatures up to 100°C.
PVDF	140°	PVDF, or polyvinylidene fluoride, is a thermoplastic fluoropolymer with high chemical and physical resistance, as well as UV resistance and flame retardancy. It is widely used in various fields, including the chemical industry, semiconductor manufacturing, and as a suture material in medicine.
C-PVC	100°	C-PVC, or chlorinated polyvinyl chloride, is a modified material of regular PVC, characterized by an increased chlorine content. This gives it improved thermal resistance, chemical and wear resistance, rigidity and chemical resistance, which makes it suitable for use in high temperatures and aggressive environments.
NBR	100°	NBR (nitrile rubber) material is often used in mechanical seals. It has very high resistance to oils, greases and other petroleum products. It provides a reliable seal between components, preventing leaks and maintaining working pressure. NBR is widely used in the automotive industry, mechanical engineering, oil industry and hydraulics.
EPDM	140°	EPDM (ethylene propylene diene monomer) is a synthetic rubber that is widely used as a material for mechanical seals in various industrial applications such as pumps, compressors and other equipment. EPDM has good resistance to water, steam, alkali and acid solutions, as well as to ozone and ultraviolet radiation.
FPM	180°	FPM (or FKM, Viton) in mechanical seals is a fluororubber with high chemical and thermal resistance, which makes it suitable for use in aggressive environments and high temperatures.
PTFE	250°	PTFE, or polytetrafluoroethylene, is often used in mechanical seals due to its unique properties. It provides high chemical resistance, a wide range of operating temperatures, and a low coefficient of friction. This makes it suitable for various applications that require reliable sealing in aggressive environments and high shaft speeds.
AISI304		Stainless steel AISI 304 analog 08X18N10. As is clear from the marking, this alloy contains 18% chromium and 10% nickel. It is the chromium in the alloy that forms acid-resistant films on its surface, which guarantees chemical inertness. Alloy 08X18N10 and its analogues can be found in food and industrial applications.
AISI316		AISI 316 stainless steel is one of the most corrosion-resistant alloys in its price segment and is widely used in industry and seal manufacturing. This alloy is a modification of AISI 304 steel, to which about 2-3% molybdenum was added. This change significantly increased the corrosion resistance of the material and made it more resistant to the effects of acids, alkalis and other aggressive environments during prolonged contact.
