Polyurethanes

Product Overview

General Description

Flexible Polyurethane Foam is one of the most versatile materials available. It is a flexible and durable cellular polymer, permeable to air flow, and offers superior cushioning properties compared to any other synthetic or natural product. Its high versatility allows it to be used across multiple market sectors such as the apparel, furniture, mattress, packaging, educational toys, and footwear industries, among others.

Flexible polyurethane foam is also known as foam rubber or polyurethane foam. Its manufacture involves the use of polyols, diisocyanates (TDI 80/20), surfactants, catalysts, and special additives.

POLIOLS

The polyols polyether Polymers are polymers formed by the reaction of organic oxides (such as propylene oxide) with an initiator that has two or more active hydroxyl groups. They are an essential component in the manufacture of polyurethanes. They are used in foams (mattresses, car seats), adhesives, sealants, and coatings. Their main advantage is greater resistance to hydrolysis and better flexibility at low temperatures compared to polyesters.

In our portfolio we handle conventional polyol (54 to 58 OH) and polymeric (28 to 32 OH) with a solids content at 45% and low viscosity.

PPG CS 743

PPG CS 743 is a polyol copolymer specifically designed for the production of conventional flexible polyurethane slab foams, automotive applications, furniture, sound absorption, and headrests. PPG CS 743 is a polyether triol graft containing approximately 451% 3% copolymerized styrene and acrylonitrile solids. It can be used in combination with conventional polyether polyols to produce enhanced, high-load foams. Foams produced with such blends exhibit a stiffness increase proportional to the level of added CPP.

PPG-3010

PPG 3010 polyether polyol is a propylene oxide triol with a nominal molecular weight of 3000, containing ethylene oxide. Its enhanced reactivity makes it well-suited for use in the production of flexible polyurethane blocks, in automobiles, furniture, beds, and hot-cure molded foam, among other applications.

TOLUENE DIISOCYANATE (TDI 80/20)

Toluene diisocyanate (TDI 80/20) is a liquid, translucent, colorless to pale yellow organic compound that is mainly used to manufacture polyurethanes, which in turn are used in products such as furniture foams, carpets, as well as coatings, adhesives and sealants.

TDI 80/20

TDI 80/20 is a chemical compound widely used in the manufacture of polyurethane foams and other plastic materials. Its full name is Toluene Diisocyanate 80/20. It has high mechanical and chemical resistance, excellent insulation capacity, and...Thermal properties, versatility in industrial applications, controlled reactivity for efficient manufacturing processes.It can be used in: construction (adhesives and binders; coatings and sealants), furniture (bedding and decoration: mattresses and pillows; medical and office furniture; paints and coatings; seats), transport (seats, headrests and armrests; paints and coatings) and wood (coating).

Rigid foam (Silicone or surfactant)

Rigid foam is widely used in construction, transportation, and healthcare, driven by the demand for insulation and lightweight materials. The main types include polyurethane foams, which are versatile and durable, and are used in panels, footwear insoles, and even medical applications.

AK-8830

AK-8830 is a non-hydrolytic polysiloxane-polyether copolymer based on silicon-carbon bonds. It is suitable for polyurethane foaming systems with various blowing agents. It exhibits excellent emulsifying, nucleating, and foam-stabilizing capabilities, achieving a perfect combination of these three properties. It also provides extremely low thermal conductivity and excellent adhesion.

AK-8812

It is a newly developed, high-activity, non-hydrolytic foam stabilizer based on silicon-carbon bonds. It is suitable for polyurethane foam systems using HCFC-141B and cyclopentane as blowing agents. It exhibits excellent nucleation capacity and a superior foam stabilizing effect.It provides excellent flow throughout the foaming process in the reaction system and produces a homogeneous density distribution. A very fine and tightly closed cell structure can be obtained in the polyurethane foam. As a result, thermal conductivity is low.

AK-8804

The foam stabilizer is a polysiloxane-polyether copolymer surfactant. It is suitable for fine microcell elastomeric systems. It can be used in polyester and polyether sole systems due to its good synthetic performance, as well as in other PU elastomeric systems. It has good solubility and emulsifying capacity in systems containing water, amine, and polyol, allows for uniform density distribution, and possesses good hydrolytic resistance and storage stability.
