Specialty additives for polyurethane flexible foam
Polyurethane soft foam is a flexible polyurethane foam with a certain degree of elasticity, commonly known as polyurethane sponge, foam. This kind of foam is elastic, generally with low density, good elastic response, sound absorption, breathable, heat preservation and other properties, mainly used in a variety of thermal materials, cushioning materials, such as cars, boats and furniture sofa seat cushions, cushions and armrests, mattresses, clothing padding and so on. Industrial and civil use of soft foam as filter materials, sound insulation materials, shockproof materials, decorative materials, packaging materials and thermal insulation materials.
Among them, the laminated composite material made of soft foam sheet and various textile fabrics is one of the classic application fields of soft foam. The composite sheet is lightweight, with good heat insulation and air permeability, especially suitable for use as clothing lining. For example, it is used as clothing shoulder pads, bra sponge pads, all kinds of shoes lining and handbag lining.
In addition, due to the PU soft foam air permeability and moisture permeability, but also suitable for the production of mattresses. For example, in our country called “Simmons” mattress, most by the PU soft foam sheet, spring and fabrics made. At the same time, because PU soft foam has good sound absorption and vibration damping performance, can also be used as sound insulation materials within the equipment.
It can be seen that the application of PU foam is everywhere, is an important material essential to life. Qingdao Deda Zhicheng Chemical Industry, as a professional supplier of special additives, has accumulated many years of experience in the field of polyurethane additives, and is able to provide customers with all kinds of solutions for polyurethane foam plastic modifiers.
Antioxidant AN6133 is a new product developed for polyurethane soft foam. As a new generation of phenol-free phosphite antioxidant, AN6133 does not contain phenol, nonylphenol, bisphenol A and other free phenolic substances. It has the advantages of low volatility, good heat resistance and hydrolysis resistance, which can effectively improve the thermal stability and anti-smoke (NOX) yellowing performance of polyurethane foam. And it can be widely used in PVC, rubber, plastic, oil and other polymers.
At the same time, Antioxidant AN6133 can also be used as efficient auxiliary stabilizer and chelating agent in soft/hard PVC materials to effectively improve its processing thermal stability and light stability, and maintain the color stability and transparency of the products. It is a highly effective antioxidant for rubber materials such as ABS, SBS, SIS, SEBS, etc.
In addition, we can also provide a variety of high-quality UV absorbers, light stabilizers and antioxidants for PU soft foam and TPU elastomers, such as Eurostar® AN6136, AN6132, AN1135, AN5057, UV1, UV571, UV1130, LS292 and so on. Through the use of a variety of additives, the synergistic effect between the additives can be fully utilized, effectively preventing the degradation of polyurethane products in the light or weather conditions, thus providing long-lasting and reliable protection.
