This resin obtained by the reaction of phenol and formaldehyde According to certain mole of ratio, firstly by reaction under alkaline condition, After the Reactions meet first step requirements, and react again under adjust to different acid condition, finally Forms the etherification modified High-ortho thermosetting phenolic resin.
This resin can storage for more long time, good wetting ability, The Curing velocity is moderate, which can apply to produce Aluminum Carbon Ramming Material, aluminum magnesium carbon Brick and so on fireproof materials. The mixed pug can store for more long time after mixed the material and this resin compared to the present market general thermosplastic liquid phenolics resin and thermosetting phenolics resin.
The Curing time and the bonding strength can satisfy the blast furnace iron-smelting and the aluminum magnesium carbon brick formation 'operation requirements.

Qingdao heli chemical Co., Ltd. is a professional manufacturer of of phenolic resin, which has been over 20 years history since it's started in 1983. We manufacture phenolic resin for refractory material, foundry(coated sand), and friction material. There are thermosetting phenolic resin and thermoplastic phenolic resin, Modified resin and other products manufactured by the company,
Our company is located in Qingdao China. Qingdao is one of the most largest ports in China. It's convenient to delivery the products.
Our company independent research and development of refractory materials used top-grade aluminum carbon products granulation binder, functional zirconium carbon granulation binder, respectively in 1993 and in 1995won the national new product award.
The refractory products made up by this kind of binder have been in place of import products of the same kind, and widely gained high praise by the customers of refractory material three great castings.
The company has passed ISO9001: 2000, quality Authentification with abundant technical strength. In "first session of China chemical industy promient brand Top 100 Recommendation Activity". The "HEDUN"Brand of our company gained the reputation of "Most competitive Brand in China Chemical Industy"The company has an excellent team of development &reseach, who could develop new products according to customers'requirements independently. In the meantime, the company own standard inspection instrument helpful to supply assured high quality. To adapt to the market development, the company has established HELI chemical industrial park in jiaozhou qingdao, and the phenolic resins reaches annual productive capacity of 20, 000.00tons. Under the principle that development is the only way to go together with initative depends on innovation, HELI people are committed to bring best ecomic benefit to relative industrial development in the ways of top-ranking remarks, high-new technology and excellent quality.
