Ramsay Rubber and Plastics Ltd
Ramsay Rubber is a specialist converter and wholesale supplier of natural rubber sponges, EPDM rubber sponges, neoprene sponges, EPDM/Neoprene blend sponges, PVC sponges and polyurethane foams for seals and gaskets, insulation, mats, impact modification, automotive NVH (Noise Vibration & Harshness) damping, weather strips, footwear, packaging and a whole host of other applications.
Materials are available in sheet form, roll form and cut shapes, with or without pressure sensitive adhesive lamination
Ramsay Rubber has broad-spectrum foam conversion capabilities. In addition to fundamental skiving & splitting, sawing, profiling, slitting laminating and adhesive bonding, we also has the capability to convert block material into continuous rolls of predetermined thickness; all in a single, economical operation.
A main focus area is the lamination of pressure sensitive adhesive to roll materials. The Company has the expertise to recommend, source and affix these adhesives to the widest range of materials.
Ramfoam manufactures a vast range of parts and components, the vast majority of which are bespoke, produced to customers' own requirements, please contact us to discuss your requirement.
Involve Ramfoam's Design and Development team at an early stage, you can benefit from our expertise in both material selection and processing techniques.
Available in a wide selection of colours, densities and stiffness.
PE foam can be blown chemically or physically expanded by the introduction of a gas such as Nitrogen, can be crosslinked, a process that enhances durability and enables them to be thermoformed.
PE foam is manufactured in sheet (bun) form or as a roll material for large volumes. Ramfoam has the facility to convert sheet material into rolls in a simple, efficient operation.
Conductive, static dissipative and flame retardant foam grades are also available as well as higher density, stiffer foams made from HDPE.
Closed Cell foams give buoyancy and enhanced thermal efficiency, enhancing physical characteristics, (strength and rigidity) while preventing water ingress and reducing water absorption.
Foams produced by nitrogen expansion give a more regular cell size and a more even cell size distribution than with chemically blown foams.
- Light weight foams that have comparable physical properties to heavier chemically blown foams
- Higher colour density with less variation throughout the sheet than chemically blown foams
- Easier and more efficient to work with.
- Enhanced physical properties when compared to foams of similar density, produced chemically.
Can be formed in a mould as a bun or manufactured in an extrusion process as roll form.
Roll foam can then be sheeted and laminated to achieve thicker equivalent buns.
Similar in many ways to polyethylene foams, EVA (Ethylene Vinyl Acetate) co-polymer foams are:
- softer to the touch,
- tougher, more resilient
- greater abrasion resistance than PE foams.
They are mainly used in a wide range of sports & leisure and footwear applications.
EVA foams can also be thermoformed into basic or more complex shapes.
Less durable than cross linked foams but have the benefit of being able to be re-melted and re-processed more easily.
Although these foams cannot be thermoformed easily they are suitable for a multitude of uses when they are cut or stamped into basic shapes.
Used extensively in one-trip packaging where they are able to cushion heavier loads than polystyrene. These foams are recyclable.
Flame retarded foam grades are available to meet the requirements of FAR/CS 25.853(a) App F Pt I.
Used in a variety of applications from building and construction to mass transit, aircraft and aerospace.
An innovative approach to traditional shielding and grounding in the electronics industry by providing X, Y, and Z-axis conductivity. It is ideal for EMI gaskets and overcomes co-planarity problems.
Conductive foam has a volume resistance less than 104 Ω (ANSI/ESD S541-2003)
Intended to protect sensitive electronic components from static electrical charge (static zap) Static dissipative foams have a volume resistance between 104 Ohms and 1011 Ω (ANSI/ESD S541-2003)
Should not be confused with 'pink' anti-static foams that depend on ambient temperature and humidity to maintain surface conductivity
Zotek® F foams are lightweight, closed cell, PVDF (polyvinylidene fluoride) foams based on Kynar® fluoropolymer, a remarkable material that offers a unique balance of properties.
- Excellent UV, nuclear radiation and ageing resistance
- High dielectric strength
- Outstanding resistance to a wide range of solvents and aggressive chemicals.
- Biologically inert
- Thermally stable across a wide temperature range (to 160ºC)
- Very low order of toxicity
Inherently flame retardant releasing very little heat and only small quantities of smoke during combustion.
Zotek® N is a range of foams based on polyamide,
They are characterised by their outstanding high temperature tolerance and their excellent resistance to attack by hydrocarbon solvents, oils and greases properties that make Zotek N a natural choice for the automotive industry.
High temperature tolerance - medical packaging designed for autoclave sterilisation.
