+358 50 386 0027As demanding industrial wear and tear resistant solutions are Teknikum specialty, the raw materials and compounds used for these are our core competence.
Teknikum’s premium rubber compound selection includes wear-resistant, acid-resistant, multi-protection and food quality rubbers.
Rubber compounds
Typical rubber compounds used in industrial applications often consist of a combination of natural rubber and various synthetic rubbers, such as styrene-butadiene rubber (SBR), nitrile rubber (NBR), or chloroprene rubber (CR). These compounds may also include fillers like carbon black or silica, as well as additives such as vulcanizing agents, accelerators, and antioxidants to enhance their performance.
The specific formulation and hardness of the rubber compound will vary depending on the desired properties, such as resistance to heat, chemicals, abrasion, or flexibility, required for the intended industrial application.

Our compounds are based on various raw materials
Natural rubber (NR)
Natural rubber is a flexible and elastic material with exceptional resilience. It has excellent elongation and tensile strength, allowing it to stretch and return to its original shape without breaking. It is also highly resistant to abrasion, tearing, and wear, making it durable and long-lasting.
Natural rubber has good electrical insulation properties and high resistance to water, weak acids and alkalis. It is used mainly where good mechanical properties are necessary.
Natural rubber is known for its sustainability and renewability. It is derived from the sap of rubber trees, which can be tapped from them. This makes natural rubber a renewable resource that can be harvested for many years from the same tree. Rubber trees grow in the tropics. For example, Malaysia and Thailand are big producers of natural rubber.
Styrene-butadiene rubber (SBR)
Styrene-butadiene rubber, also known as SBR, is a synthetic rubber. SBR exhibits commendable abrasion resistance, tensile strength, and resilience. Its aging stability is better than NR, allowing it to resist deterioration over time, especially in the presence of heat and environmental factors.
SBR rubber is a versatile synthetic rubber widely used in various industries, particularly in tire manufacturing. Its desirable properties and cost-effectiveness make it a popular choice for a range of applications.
EPDM rubber
EPDM rubber (Ethylene Propylene Diene Monomer rubber) is a synthetic elastomer known for its excellent weather resistance, ozone resistance, and heat resistance. It can withstand temperatures ranging from -40°C to 150°C (depending on recipe), making it suitable for both indoor and outdoor applications. It has excellent electrical insulation properties and is resistant to chemicals and UV radiation.
EPDM rubber exhibits moderate mechanical properties and good electrical insulation properties. It is also known for its low compression set, meaning it returns to its original shape after compression making it a suitable option for sealing applications.
Butyl rubber (IIR and BIIR)
IIR rubber, also known as butyl rubber, exhibits excellent impermeability to gases and liquids due to its low gas and vapor transmission rates. It also offers good resistance to heat, weathering, ozone, and chemical attack. IIR rubber has a low degree of unsaturation, making it highly resistant to oxidation and degradation. Additionally, it has good electrical insulation properties. However, IIR rubber has relatively low resilience and poor resistance to petroleum-based oils and hydrocarbon solvents. BIIR rubber is brominated version of butyl rubber and it has mostly similar properties than IIR.
Nitrile rubber (NBR)
Nitrile rubber, also known as NBR (acrylonitrile-butadiene rubber), is a synthetic rubber copolymer made from butadiene and acrylonitrile. It is characterized by its excellent oil and fuel resistance, making it a popular choice for applications in the automotive, aerospace, and oil industries. Nitrile rubber also possesses good resistance to chemicals, heat, and abrasion, making it suitable for a wide range of sealing and hose applications.
Additionally, NBR is commonly used in the manufacturing of gloves for medical, industrial, and laboratory purposes due to its resistance to oils and chemicals.
Chloroprene rubber (CR)
Chloroprene rubber, also known as neoprene, is a versatile synthetic rubber with unique properties. It exhibits excellent resistance to weather, ozone, and chemicals, and moderate oil resistance, making it suitable for a wide range of industrial applications.
Chloroprene rubber has good mechanical strength and is highly durable, with good tensile strength. It maintains its elasticity and flexibility over a wide temperature range, from -40°C to +110°C.
Additionally, it has good flame resistance and low gas permeability, making it suitable for sealing and insulation purposes. Overall, chloroprene rubber is a reliable and efficient material in various industries.
Teknikum® rubber compounds are developed and manufactured in Finland according EU chemical regulations.
