At SealingTechnologies, “materials” form the backbone of our technology. Every day, people interact with products featuring seals, often with little knowledge about the materials they're made from. For instance, plastic, a relatively modern material, has long been hailed as a “wonder substance.” But what makes plastic so flexible, and how are its various formulations distinguished? When is a silicone seal from SealingTechnologies superior to one made of polyurethane or rubber?
As a worldwide sealing technology leader – with vast resources and experience – Freudenberg is uniquely positioned to provide exceptional engineering, manufacturing and customer support wherever you do business.

ACM Elastomers are made of polar arcylic acids. As polar materials, they display good resistance to high-additive lubricating oils
Thanks to its excellent stability in water and aqueous solutions, EPDM is one of the most widespread materials in the food and pharmaceuticals industry with its share of approx. 70 percent.
With Simriz® perfloroelastomer, Sealing Technologies offers the processing industry the High-End solution in materials technology for sophistricated applications regarding media and temperature stability.
Because of their wide range of compounding possibilities, FKM materials from Freudenberg Sealing Technologies offer great flexibility to suit the respective customer-specific application.
Fluoroprene® XP is the premium allrounder amongst our quality materials, which unifies the advantages of EPDM and FKM particularly cost-effectively.
HNBR is produced through the selective hydrogenation of NBR. The reactive double bonds are removed from NBR.
It is used for oil- and fuel-resistant seals such as Simmerrings, O-rings and frame seals. The use of NBR marked the arrival of elastomers as a sealing material particularly in general industry.
In its original form, latex is greasy and sticky. Natural rubber is an elastic polymer, built on isoprene as its monomer.
Polyamides offer high strength, rigidity and durability with good chemical resistance and processability. They feature high resistance to wear and good anti-friction properties.
PAI is a thermoplastic that has high strength and stiffness up to 275°C while offering outstanding resistance to creep, wear, and chemical attack.
PEEK offers similar chemical stability to PTFE, however has better mechanical properties. A material which is becoming increasingly popular in processing technology due to its stability at high temperatures.
POM stands out for its high strength, hardness and rigidity over a wide range of temperatures. It even maintains its durability at low temperatures.
PTFE from Freudenberg Sealing Technologies is very impressive with its great media stability and can be optimized for the respective application by blending it.
Polyurethanes offer an alternative in cases where rubber elastomers cannot be used or where highly specialized elastomers are out of the question for cost-related reasons.
VMQ silicone elastomers are used in demanding thermal applications, and, due to their purity, are especially suited for hygienic uses in the food and pharmaceutical industries.
