What is Polyurethane

Polyurethane is found in various forms:
castable elastomers
rigid or flexible foams
adhesives and sealants
liquid coatings and water born dispersions
Clifton Rubber manufacture parts using castable polyurethane elastomers. These elastomers are a synthetic material that possess elastic characteristics like a high performing natural rubber. They are extremely versatile materials that can yield different properties dependant on the system used, either rigid or flexible, hard or soft, resilient, durable and hard wearing.
We process both Ester and Ether PU castable systems with an MDI base material, which is the material of choice for a broad range of end-user applications. The classification of hardness for polyurethane relies on the prepolymer’s molecular structure and we can manufacture parts from 55 Shore A to 85 Shore D. It is possible to manufacture parts with a lower Shore A hardness by adding certain additives to the mix.
Colour pigments can be added to the mix to enable a customer to specify a specific colour for their parts.

An Introduction

We have extensive experience in the design, development, prototyping and manufacture of polyurethane products and can manufacture almost any product required from our moulding, casting and coating processes.
Our expert technical team can assist in the design and development of any required polyurethane item, working with our customers to provide a high quality and dependable product solution. We produce components for various applications in all major industries including offshore, automotive and transportation worldwide.

The Polyurethane Moulding Process

We process polyurethane using the two principal methods of open pour casting and closed injection moulding. Each process has key benefits depending on order volumes, product complexity and the required physical properties of the component’s end use.
This production flexibility means that we are best placed to provide our customer with the best solution whether producing high volumes or single run bespoke items.
Our in-house precision engineering unit offers the capability to design and manufacture unique open and closed mould tools to meet all product requirements. Our mould tools are manufactured from durable alloys to ensure they produce quality products every time over many years of service..

The Product Produced

We have produced many custom products to match customer requirement. Our most common products include:

Wheels

Buffers

Coatings

Rings

Rods

Sheets

APolyurethane Moulding Materials

We manufacture bespoke products using a range of elastomer based polyurethane systems each with a specific chemical formulation depending on the required application and service environment of the end component. Our systems include both MDI and TDI Isocyanates, Polyester and Polyether Polyols.
Our processing equipment has the capability of varying the hardness of our materials anywhere within the range of 50 Shore A to 80 Shore D, and colours can be specified to suit the customer requirements, with commonly specified colours being: Black, Red, Yellow, Green, Orange and Blue.
The polyurethane materials we use in our casting and moulding processes are sourced from the industry’s leading suppliers and are supplied to us having been tested and approved to the highest standards.
