Foam with the addition of anti-static agents to prevent electrostatic charges. The foam is particularly useful for packing electronics.
The foam material is produced in a continuous process in large blocks which are then cut, split and glued to the desired shape. Carpenter’s block foam manufacturing includes conventional polyether, high-resilient grades, hypersoft and viscoelastic foam.
Foam that has been shredded into small pieces and compressed under high pressure in a mold using adhesive. Using this method, various types of bonded foam can be produced in densities from 40 up to 450 kg/m3.
(Freon) expanding agent that has been prohibited in the manufacture of foam plastic in Sweden since 01/01/1991.
Abbreviation for Combustion Modified High Resilience. High resilience foam that Is flame retarded to meet the requirements set in the English fire safety regulation, “Consumers Protection Furniture and Furnishing (Fire) (Safety) Regulation 1988, Schedule 1, Part 1, ignition source 5.” Legal requirements for furniture sold in the UK and Ireland.
TDI (Toluene Diisocyanate) and MDI (Methylene Diphenyl Diisocyanate) used in the manufacture of foam.
Flame retardants are added to some types of foam during the foaming process to improve the foam’s ability to to retard the ignition of the foam product. Flame retardants are added to meet specific fire test standards.
The raw materials are premixed and injected into a mold, after which they expand to form a finished foam pad or component. All our production of molded components are made of highly resilient material. The cost of mold production means that molding is often only possible for larger series runs.
Substances such as chlorine, fluorine, bromine and iodine. Used as flame retardants for foam.
The trademark for an extremely soft type of foam. Hypersoft® foam also has a high ultimate tensile elongation and a very high level of comfort.
Often referred to by the abbreviation HR for high resilience. High resilience foam gives a better comfort feel than conventional polyether and in most cases it also has better durability. Also known colloquially as cold foam.
Curing agents in the foaming process. See also TDI and MDI.
Rules developed by the International Organization for Standardization.
Foam was originally molded by the mold being heated (hot cure). The method was then refined to allow molding without added heat (cold cure). The same method and some of the same raw materials were later used for the block foam process which is why it was named, albeit incorrectly, cold foam (cold cure). The correct name should be highly resilience foam.
Conventional foam are standard products within the polyether family for the majority of applications.
Carpenter Sweden AB currently meets ISO 9001:2000
Methylene Diphenyl Diisocyanate.
Carpenter Sweden AB currently meets ISO14001.
Foam is divided into two families – polyether and polyester. Polyester has a more regular cell structure and is primarily a product used for industrial purposes. Its resistance to oil, grease and solvents gives it a multitude of uses.
Polyether foam has an irregular cell structure and has very good comfort properties. The best applications for polyether are in the furniture and bedding industries. Polyether performs well in damp and wet environments.
The generic chemical name for the type of polymer that our foam comprised. Polyurethanes can be used in many application areas, ranging from homogeneous truck wheels to the elastic fiber in swimwear.
The correct name for our foam is flexible polyurethane foam.
Systematic fire prevention work is conducted in accordance with the law on accident prevention and the Swedish Civil Contingencies Agency’s general advice and comments.
Health and safety legislation contains rules on how to conduct systematic occupational health and safety practices.
Foam can, under normal air conditions, be used in temperatures from -40°C to +120°C.
Polyether foam is discolored to varying degrees by ultraviolet light.
Also known as viscous foam or healthcare foam. Foams with extremely little elasticity. Used in mattresses and pillows where you need a very special pressure relieving feeling that this foam will provide. Carpenter’s trademarks for viscoelastic foam are Celsius® and Isotonic®.
When foam is tested this often involves a testing standard where the material must have aged before the test. This occurs at a certain temperature for a certain period and at a certain air humidity.
Foam has a high energy content and is suitable for energy recovery when this occurs in an approved incineration facility.
