Polyurethane

Polyurethane products are a tough but gentle alternative to rubbers, plastic and in many cases metals, where extra life is required in arduous applications. Polyurethane shore hardness can be softer than a pencil rubber, harder than nylon or anywhere between.

Since a variety of diisocyanates and polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applications.

BENEFITS OF POLYURETHANE PRODUCTS 

Polyurethanes are a very versatile elastomer, or artificial rubber. Chemistry can change the properties of a substance, allowing it to take on a variety of different characteristics. Polyurethane’s versatility is its main advantage over all other products. Below are the main benefits and advantages of using polyurethane:

• Longevity
• Abrasion Resistance
• Affordable Manufacturing Process
• It is a Very Tough Material
• Oil and Chemical Resistance

POLYRETHANE PRODUCTS WE PROVIDE

Aquaseal Rubber Ltd manufactures the following polyurethane products:

POLYURETHANE OPEN-CAST MOULDING

Open-cast urethane and polyurethane moulding can produce a wide variety of products for most industries.

Urethane and polyurethane surpass most other polymers for applications requiring:

• high abrasion resistance
• outstanding tensile and tear strength
• noise dampening
• chemical resistance
• excellent load-bearing capability

Urethane can replace expensive metal casting. It is lightweight and still maintains or exceed wear characteristics found in their metal counterparts. We can make polyurethanes to maximise particular specifications. This includes maximising abrasion, and increasing tensile strength to get a strong, break-resistant part.

The ingredients in some urethanes are FDA approved for contact with foodstuffs. This means they can be used in food services and production as well as the medical industry.

URETHANE ROUND BARS

We offer many sizes of polyurethane and urethane rods, ready to ship within a few days. These are at competitive prices and in a wide range of durometers. Our standard pricing covers durometers from 50-100 on the “A” scale and up to 60 on the “D” scale. We have special pricing for softer and harder urethanes.

POLYURETHANE SHEETING

Polyurethane sheeting can be produced in a variety of dimensions. There are many methods used including centrifuged, flat cast, moulded and extruded.

Applications include:

• cutting or punching gaskets
• scrapers and flaps
• protecting industrial table tops
• lining wear chutes
• blast cabinets

HOW WE DO IT:

• Polyurethane, dispensed in liquid form into heated moulds, from modern dispensing machines
• After heat curing, parts are trimmed or machined finish
• This process produces the most durable urethanes
• Mould costs will generally be comparatively low
• Widest shore hardness range (10°A to 95°D)
• Natural (translucent) or pigmented components in a wide range or colours (to RAL specification if required)
• Process suits high or low volume production
