Wanhua Chemical: Bonding your core PUR s method of mattress compounding

A good night’s sleep with comfort and decompression is the common pursuit of many people. In order to meet consumers’ differentiated needs for hardness, support, and comfort, mattresses made of different materials have become the most common type on the market, and environmentally friendly and efficient adhesives are the most common type of mattresses for this type of mattresses. Indispensable part.

PUR (polyurethane
reactive) is the abbreviation of reactive polyurethane hot melt adhesive. This solvent-free adhesive reacts with the air or the moisture in the substrate and the active hydrogen on the substrate to produce physical and chemical bonding at the same time to realize the bonding between the substrates. compound. Wanhua Chemical has innovatively developed the WANNATE® series of PUR products to provide high-performance and environmentally friendly options for mattress composites.

Sponge mattress compound

Sponge mattresses are made of multiple layers of sponges of different materials, such as slow-rebound sponges, high-rebound sponges, imitation latex sponges, etc., and are generally compounded by roller coating. Wanhua Chemical launched WANNATE®
Compared with the traditional environment-friendly glue, the 6019 series products help customers reduce costs and improve efficiency with more efficient and rapid composite processing, automated sponge composite production lines and fast-paced site turnover.

WANNATE® 6019 Series

Compound Spring Mattress

Spring mattresses are usually divided into a comfort layer and a structural layer, and the composite process is mainly spray glue. Traditional thermoplastic hot melt adhesive products liquefy and infiltrate the substrate after heating, and solidify after cooling to form a physical bond. Abnormal noise.

Wanhua Chemical launched WANNATE® 6028 and WANNATE®
6259 series PUR, as a thermosetting product, can react with active hydrogen in the substrate to form a chemical bond while infiltrating the substrate. The temperature resistance can reach 150~200°C, which effectively solves the problem of high temperature anti-sticking.

WANNATE® 6028 & 6259 Series

In the future, Wanhua Chemical will continue to take technological innovation as the driving force and rely on the advantages of the upstream and downstream integrated industrial chain to provide customers with more green and high-performance PUR products and solutions, and promote the healthy and sustainable development of the industry!
