Elastomeric innovation for industry: materials and manufacturing for the future
Martin’s Rubber keeps a careful eye on various industries and raw material producers to identify new developments in the fields of polymer technology and manufacturing techniques.
Some of our recent materials development projects are as follows:
Martin’s Rubber is exploring the benefits of utilising modern-day nanomaterials, such as plasma functionalised multi-wall carbon nanotubes and graphene nanoplatelets.
Through use of these functionalised nanomaterials we have improved the damping in dynamic conditions on a bespoke formulation. The optimised compound is also lighter, shows improved strength and elongation all whilst maintaining compression set resistance. Download our recent study results on the panel at the right hand side of the page; our study was carried out in conjunction with Haydale Ltd using their HDPlas™ functionalised multi-wall carbon nanotubes (MWCNT) in conjunction with an HNBR to find out some of the specific benefits already uncovered.
These lighter, stronger materials with improved damping characteristics can be used to benefit a wide variety of applications.
Martin’s Rubber is also investigating the use of other 2D nanomaterials for enhanced thermal conductivity, and retained electrical insulation. This technology can be used to dissipate heat in electrical systems.
FRlite® is an innovative silicone that uses novel compositions and syntactic technology to reduce part weight by an unprecedented 25%.
Unlike closed cell porous sponge materials, this material utilises a self-reinforcing porous structure to reduce the density, without compromising on the characteristics of solid rubber. The porous structure resists collapse, so load is transferred through the bulk of the elastomeric material as with conventional solid rubber. This lighter material retains the load-deflection and compression characteristics of solid rubber, providing the opportunity to utilise shape factor for engineering solutions.
RF/EMI Shielding Materials
EMI (electromagnetic interference) shielding components are commonly used when sensitive electrical equipment needs to be shielded from external RF fields along the seams and apertures of an enclosure. These components are used across many industries, including aerospace, defence and medical.
Martin’s Rubber can produce bespoke 3D shapes in a wide variety of materials, including several MIL-DTL-83528C certified grades.
Martin’s Rubber is exploring the use of ferrimagnetic fillers for magnetoresponsive components. Through use of various ferrites, the coercivity of these materials can be tailored to the application. These materials have many applications in a variety of industries, such as automotive and food & pharma.
- With increased demand in the automotive industry for oil-resistant materials suitable for higher temperatures, Martin’s Rubber has evaluated the next generation of ethylene-acrylic rubber. Using novel pre-compounded filler materials, these elastomers push the limits on working temperatures to ensure the continued high performance of modern vehicles and support the next generation of automotive developments.
- Martin’s Rubber has identified the latest generation of EPDM materials, characterised by their very high molecular weight. These elastomers display remarkable physical properties, approaching those of natural rubber, whilst offering the same temperature and chemical resistance of current EPDM materials.
