ISO 9001- Certificated compounds KTW-ACS-WRAS-KIWA Certificable compounds UBA 2021

AGR is a small production company specialising in, both compression and injection, moulding of gaskets and technical products in rubber and silicone.

The company was founded in the 80s, taking over the plants from another company and intends developing other production technologies, beginnin with compression moulding. In the following years, it also invested and developed injection moulding while maintaining and growing in compression.

Certification ISO 9001:2015

Today AGR is able to actively participate in the development of any project with the prototyping of samples and the production of the necessary equipment for production start-up.

AGR, with the consultancy of the best suppliers of mixtures, is able to test and validate special rubbers for every possible use, issuing certificates and declarations for use in compliance with the various reference regulations.


AGR is able to transform any type of rubber compound such as:



from 30 to 90


from 30 to 80


from 30 to 80


from 30 to 80


from 20 to 90


from 50 to 80

Taking into account that each type of polymer can be made using several formulae, completely different from one another in colour, hardness, physical/mechanical characteristics, the end products can have different degrees of surface finish.

AGR also collaborates with the top companies in production of extruded products, profiles and finishes, (cutting, glueing, marking, packaging) and we also act as a project leader for various products, always in the field of rubber.


Natural or synthetic, rubber is a material that, once vulcanized, maintains higher elastic values compared to any other similar product.

Elastic values are defined by: lengthening/breaking load/tear resistance, elastic return, compression set.

A gasket is normally a sealing element between two or more surfaces coupled or moving and the choice of the material depends on the temperature, contact products and general conditions, as well as the cost.

The most commonly used materials are:
(ASTM nomenclature)

  • ACM
    Polyacrylic excellent resistance to low temperatures (-30 degrees Celsius) and high temperatures (180 degrees Celsius) Oil and oil derivatives/ozone/gas/water
  • CR
    Polychloroprene (commonly known as Neoprene®) From-15 to 120 degrees C Good resistance to oils/alkali/ultraviolet ozone, gases, chemicals. Great mechanical features
  • CSM
    Polyethylin commonly chlorinated Hypalon® Good thermal characteristics (-30 to 150 degrees Celsius)
  • EPDM
    Terpolimer by Ethylene Propilene (commonly Dutral®) Excellent resistance to weathering, good thermal resistance, excellent insulation characteristics (-60 to 150 degrees Celsius)
  • EPM
    Ethylene Propilene Copolimer Essentially similar to EPDM
    Fluoroclastomero With particular formulae you can get to limit temperatures of use (-45th to 320 degrees Celsius) Excellent resistance to fuels, hydrocarbons, oils, acids and bases, solvents. Low gas permeability, excellent electrical characteristics, low inflammability
  • NBR
    Nitric Gum Copolypoly Butadiene Acrylonitrile Infinite prescriptions can change its characteristics. Generally excellent resistance to mineral oils/fats, benzines with good mechanical characteristics (-50 degrees Celsius)
  • HNBR
    Hydrogenated nitrilic gum Good abrasion resistance, good compression set. Good thermal strength (-40-150 degrees C) Good resistance mineral oils, hydrocarbons, water, steam, gas, vegetable oils
  • NR
    Natural eraser Poor thermal strength (-70, 80-C) excellent mechanical characteristics for wearing, tearing, cutting, stretching. Suitable for contact with food
    Silicone gum is the most extraordinary rubber for the most demanding uses. Thermally exceptional (-100FMG at 315 THT) high insulation, but also conductive, odorless, tasteless, contact foods, skin and pharma. Medium Mechanical Characteristics
  • SBR
    Styrene/Butadiene Alternative to NR rubber with better thermal strength but lower mechanical characteristics (-40 C, 100 degrees C) Resistant to brake liquid/silicone/dense oils
    Etil Acrylate (commonly Vamac®) Good temperatures of use (-40 to 180 degrees C) Resistance to oils, refrigerant liquids, acids, weathering.

Different formulations can be evaluated for each of the above listed rubbers that can resolve each type of request.

Application areas

AGR, in its 35 years of activity, has created and continues to produce what the market demands with products ranging in:

With technical items and seals from the least exepesive rubber to the one specially made for the most difficult solutions with mixtures responding to the most requested national and international regulations FdA, BgVv, Wras, UL, Moca, ASTm, BS, etc...
