SILSURE Antimicrobial Silicone | Silver Ion Silicone Rubber

Antimicrobial Silicone

Independantly Tested to Reduce Bacterial Growth

SILSURE Antimicrobial silicone releases a stream of silver ions that inhibit bacterial growth on its surface. In light of the COVID-19 pandemic, Polymax are offering this material for use in medical, healthcare and pharmaceutical settings.

How Does It Work?

As bacteria or microbes make contact with the SILSURE surface, the free silver ions break down their cell walls, inhibiting the growth of any micro-organisms. The material simultaneously breaks down the bacteria whilst preventing further colonising on its surface, thus providing ongoing protection.

Independent Test at 30°C:

(% change compared with initial inoculum):

After 6 hours:
  • E.coli > 99.99% Reduction
  • MRSA > 85% Reduction
After 18 hours:
  • E.coli > 99.99% Reduction
  • MRSA > 99.99% Reduction


SILSURE is a sold 60 Shore A specially compounded FDA complaint rubber sheet and has been developed to produce silicone products with resistance to bacterial growth and then to actively break down the growth of bacteria/ organisms such as E-coli, MRSA & salmonella in accordance to JIS Z 2801:2000. These products meet the flammability requirements of FAR 25/ JAR25/ CS 25 Appendix F, Part 1, (a)(1)(iv) and (a)(1)(v) and (a)(1)(v) horizontal flammability tests.

SILSURE can be supplied in a sheet form or as bespoke moulding/ extrusion. We have a wide range of presses, CNCs and oscillating knife cutters with the help of which we are also able to provide bespoke gaskets, strips and seals from this material cost-effectively.
