Foam Product Types

POLYURETHANE FOAM (Flexible open cell foam)
Polyurethane foam can be used for upholstery, bedding, seat cushions, motor trimming and carpet underlay. Stocked in a wide range of grades from light, short term use grades to the premium/enduro (long lasting) and specialty foams (e.g. combustion modified) these can be supplied cut or in sheets. Ask for advice about the best foam to suit your application and budget.

Polyurethane foams are stocked as mattresses (commercial quality), as shaped pieces (e.g. backrests, wedges, bolsters etc.), and in convoluted surface finishes (e.g. mattress overlays, invalid comfort cushions etc.).
Application: Polyester foams are specialty foams for acoustic and filtering purposes. Properties can include flame retardancy, fuel and oil resistance and differing grades of coarseness. Polyester foams have a shorter life than the polyurethane foams which have replaced them for general use. Meracell foam is for filtering air, water or fuel. Reticulated foam is for fish tank system filters. Acoustic foam is available in a flat or convoluted surface finish.
Application: Closed cell foam has diverse characteristics such as buoyancy and water resistance. It is resistant to petrol, oil and most chemicals, shock abosorbent, UV resistant and insulates against heat and cold. It is therefore used in many applications. 

EVA, polyethylene and various blends and laminates of closed cell foam are stocked in sheet, on the roll, and in product form (e.g. boat fenders, foil faced insulation, expansion joint fillers, sealing strips, grip matting).
Application: Packing material which also has insulating properties. It lacks the flexibility of closed cell foam in that it is 'crisp', but is a cost effective alternative in static applications. Stocked in sheet thicknesses of 10mm to 100mm. Other sizes and thicknesses supplied to order.
Understanding Foam Codes
Foam codes are expressed as two sets of numbers
e.g. 23-130. The first number (23) indicates Density, the second (130) indicates Hardness. There can sometimes be prefixes and suffixes. For example H42-500 where the H designates Heavy Duty and HR32-130CM where HR indicates High Resilience and CM that it is Combustion Modified.
Density is not necessarily related to hardness as it is possible to produce, from super soft through firm to rigid foam, all of the same density. The density is a guide to the foam's durability (or quality), the rate and extent of its hardness and height loss in service. Density is a measure of the mass per unit volume and expressed in kg/m3. The higher the number, the better the quality, the longer it lasts and ……. the more you pay for it!

Hardness In most situations, the choice of foam for a certain application is decided on hardness. Foam is tested for load bearing and graded accordingly. A typical choice for 150mm thick lounge seating would be 130 hardness. For dining chair seating is 50mm thickness and 200 hardness is the most common choice.
