Whilst silicone rubber is undeniably an extremely popular and versatile material for a wide range of applications, at CB frost & Co, our expertise and product range extends far beyond Silicone. As specialists in rubber and plastics manufacturing, we pride ourselves in supplying and converting a vast array of high-performance materials, tailored to meet the exacting demands of virtually every industry. 

Don’t limit material selection

Silicone rubber stands out as a high-performance material, offering exceptional resistance to extreme temperatures, UV radiation, and a wide range of chemicals. This combination of properties make it a go-to choice for countless critical applications across modern industries, from aerospace and automotive, to electronics and medical devices, where reliability under harsh conditions is non-negotiable. 

At CB Frost & Co, we excel in providing custom silicone solutions, however, it’s vital to acknowledge that while silicone materials are incredibly versatile, limiting your material choice to only silicone can mean missing out on the unique advantages that other specialised elastomers and polymers bring to the table for different, but equally demanding applications. This is why we stock and convert a wide selection of specialist materials, ensuring you get the perfect compound for optimal performance, longevity, and cost-effectiveness.

Rubber

Commercial and synthetic rubber materials offer a myriad of benefits for industrial applications across various sectors. Natural rubbers are well suited to components requiring high elasticity, tensile strength, and excellent dynamic properties, ideal for vibration isolation and shock absorption. 

On the other hand, synthetic rubbers are engineered to provide specific properties, such as superior resistance to oils, chemicals, extreme temperatures, UV radiation, and ozone, often outperforming natural rubber in harsh environments. This diverse range of properties ensures that whether the application demands flexibility, chemical inertness, weatherproofing, or robust durability, there’s a rubber compound perfectly suited to enhance performance, ensure safety, and extend the lifespan of industrial components and systems.

We supply and convert an array of rubber materials, including:

  • Silicone Rubbers
  • Neoprene Rubber
  • Nitrile Rubber
  • Commercial Rubber
  • Commercial Insertion Rubber
  • EPDM Rubber
  • Fine Fluted Ribbed Matting

Sponge

With their unique cellular structures, sponge rubber materials offer a range of benefits across many industrial applications. Their compressibility allows them to conform to irregular surfaces, making them ideal for use in sealing against dusty, water and air ingress, as well as providing cushioning and shock absorption to protect delicate components.

Depending on whether they are open-cell or closed-cell, sponge materials offer versatile solutions for temperature management, noise reduction, and lost-lasting performance in demanding environments, due to their resilience and resistance.

We stock and manufacture with various sponge materials, including:

  • Silicone Sponge materials
  • Neoprene Sponge
  • EPDM Sponge
  • PVC Sponge
  • Nitto Semi-Closed Sponge

Foam

Foam rubber materials offer many industrial advantages. Their unique open-cell or closed-cellular structures provide excellent properties like cushioning and shock absorption, making them ideal for protecting delicate components and reducing impact. Foam materials also provide thermal and acoustic insulation capabilities, helping regulate temperature and dampen noise in a range of environments, from HVAC systems to automotive or rail interiors. 

Certain grades of foam materials can also offer good resistance to moisture, chemicals, UV, and extreme temperatures, ensuring durability and long-lasting reliability even in demand industrial settings.

We regularly supply and convert foam compounds such as:

  • Silicone Foams
  • Polyethylene Foams
  • Polyurethane Foam
  • Armaflex Foams
  • Class O Insulation Foam
  • PORON Urethane Foam

Plastics

Beyond rubber, sponge and foam materials, we also work with various high-performance plastics to provide comprehensive machined solutions, including:

  • Sustamid 6 FT (PA6)
  • Machined PVC
  • Machined Nylon
  • Acetal Plastic
  • PTFE

Your High-Performance Material Needs

Our commitment is to guide you through the material selection process. Our experienced team will work closely with you to understand your application’s specific environmental conditions, mechanical stresses, chemical exposures, and regulatory requirements. This ensures that whether you need the extreme temperature stability of silicone, the oil resistance of nitrile, or the weathering resilience of EPDM, we can provide the optimal high-performance material in the precise form you need – be it sheeting, strips, gaskets, or custom mouldings.

Don’t settle for a one-size-fits-all approach. Explore the full spectrum of possibilities with CB Frost & Co.
