Materials

Gallford Limited are able to offer a wide range of materials that meet a broad range of industry specifications.

This allows us to offer:

Rigid Extrusions

Examples of materials extruded include:

• PEEK: High temp, high chemical resistance, high abrasion resistance. Used in very specialist applications.
• Polycarbonate PC: High temperature, high impact, easily coloured can be modified for UV, low chemical resistance.
• PVC-U: Commodity material for general purpose, can be modified for impact strength, UV resistance and easily coloured.

Flexible Extrusions

Examples of materials extruded include:

• Polyurethane PU: Excellent fuel resistance, excellent flex fatigue resistance, can be modified from very flexible to very rigid, can be clear or coloured, can be formulated for very specific properties and environments.
• PVC: Can be coloured and can be modified to enhance the technical characteristics for certain applications. Commodity material for general purpose usage and low demanding technical applications.
• TPE: Can be formulated to be specialist or commodity and each formulation is based on a specific technical requirement.

Rubber Extrusions

Examples of materials extruded include:

• EPDM: Has high and low temperature resistance, good deflection recovery or compression set, excellent weather resistance and UV and ozone resistance. EPDM is in a sense a commodity material but the properties can be modified many ways to enhance specific properties.
• Neoprene: Neoprene is similar to the above but has particularly good fire resistance.
• Sponges: Are all similar to the above but has the advantage of very low density i.e. weight reduction or light compression requirements.

Material Selection

Many material types can be modified to enhance certain performance characteristics. To help determine the material type most suitable for your application there are a number of questions that need to be asked to determine the requirements of the final product.

The material can be defined when the answers to some of the following questions are known.

• What does it do?
• What temperature range is it going to see?
• What chemical resistance does it require?
• What climatic conditions is it going to see? i.e. Very high UV, very cold temps etc?
• What does it need to be compatible with, what other materials will it be in contact with?
• What impact strength is required and under what conditions?

The more information you are able to supply us the easier it will be to make an informed choice for the correct and most cost effective material.
