Materials

Synthetic rubber with exceptional behavior against lubricants, which makes it a first choice for seals and O-rings. Limited resistance to weathering and acids.

Most common temperature range from -30 ºC to +110 ºC.

Special formulation: -60 ºC to +135 ºC.

Synthetic rubber with good resistance to hot water, steam, ketones and brake fluids, among other products. Good electrical insulator. Strong incompatibility with lubricants, so it is not used as a seal material.

Most common temperature range from -35 ºC to +150 ºC.

Special formulation: -50 ºC up to +288 ºC

This material is popularly known as viton. It has good resistance to lubricants, fuels and acids and bases, among other products. Peroxide-cured formulations improve its resistance to incompatible fluids such as alcohols and steam. It is a material widely used as seals and O-rings that stands out for its low permeability to gases.

Most common temperature range from -20 ºC to +210 ºC.

Special formulation:

• -51 ºC to +225 ºC.
• -15 ºC to +250 ºC.
  

This material is popularly known as Aflas®. Synthetic rubber with exceptional resistance to hot water, steam, acids, lyes, ammonia and brake fluids, among other products. It is not compatible with ketones, gasoline, ethers and solvents.

Most common temperature range from -5 ºC to +230 ºC.

Special formulation: -25 ºC to +250 ºC.

Synthetic rubber that stands out for improving the mechanical properties of NBR as well as its chemical resistance to steam, oil and weathering. Good abrasion resistance. Limited resistance to strong acids, ketones and aromatic compounds.

Most common temperature range from -35 ºC to +150 ºC.

Special formulation: -55 ºC to +160 ºC.

This material is popularly known as neoprene. It has good resistance to weathering, lubricants and ammonia, among other products. Good resistance to abrasion.

Most common temperature range from -40 ºC to +100 ºC.

The most outstanding feature of polyurethane is its resistance to abrasion and together with its wide resistance to lubricants, polyurethane is used in the manufacture of scrapers, rod collars, piston seals for hydraulic services (light, medium and heavy). Hydrolysis (water attack) resistant formulations are available.

Most common temperature range from -25 ºC to +110 ºC.

Special formulation: -55 ºC to +115 ºC.

This material combines the almost universal chemical resistance of Teflon with the elasticity of fluoroelastomer. It is only molded as an O-ring. However, there are formulations that withstand temperatures in excess of +325 °C.

Most common temperature range from -15 ºC to +275 ºC.

Special formulation:

• -46 ºC to +250 ºC.
• -15 ºC to +327 ºC.
  

Methyl vinyl silicone rubber with outstanding thermal resistance and good cold flexibility. Good electrical properties. In general, its chemical resistance is poor. It is usually used in cryogenics.

Most common temperature range from -60 ºC to +250 ºC.

Special formulation: -100 ºC to +250 ºC.

Fluorine methyl vinyl silicone rubber that maintains good cold flexibility and improves the chemical resistance of silicone (VMQ) to organochlorine and aromatic compounds. Very good resistance to weathering and vegetable oils.

Most common temperature range from -55 ºC to +225 ºC.

It is the only non-synthetic rubber obtained from a milky emulsion contained in the sap of the Hevea Brasiliensis tree. Its main application is as a vibration and noise insulator. It is an electrical insulator and withstands water, acids, bases and lyes. Incompatible with lubricants and weathering (biodegradable).

Most common temperature range from -60 ºC to +80 ºC.

This material is popularly known as Teflon. It is a thermoplastic (non-elastic) material with almost universal chemical resistance. It has a very low coefficient of friction and is practically non-stick. The problem of creep is largely solved by adding fillers such as graphite, coking carbon and glass fiber, among others, to the virgin PTFE.

Most common temperature range from -200 ºC to +260 ºC.
