1. Introduction to Weilin Stock
Puyang Weilin Chemical Co., Ltd. (hereinafter referred to as “Weilin”) was established in 1998 with a registered capital of 77.56 million yuan and is located in Hubuzhai Fine Chemical Industry Park, Puyang, Henan. The company is a key high-tech enterprise of the National Torch Program, an innovative enterprise in Henan Province, a demonstration enterprise of energy-saving and emission reduction technology innovation, a demonstration enterprise of technological innovation, a hundred-high enterprise, and an AAA-level industrial enterprise in Henan Province in terms of quality and credit.

The flame-retardant polyol for polyurethane researched and developed by Weilin Co., Ltd. has created a new era of flame-retardant polyurethane products with endogenous structures, and has received widespread attention in the industry. Weilin Flame Retardant Polyol has both excellent thermal insulation and flame retardant properties, and stable storage performance. The products are widely used in rigid polyurethane building boards, spray foam, pipe insulation, refrigerator cold storage and other insulation systems.

2. R&D background: transformation and upgrading, pragmatic innovation
Polyurethane rigid foam has low thermal conductivity, good mechanical properties, and light weight. It is an internationally recognized high-performance thermal insulation material. Due to its poor flame retardancy, it is difficult to reach GB8624-2012 B1 level The various indicators of GB50016-2014, as well as the requirements of GB50016-2014 building fire protection design code, therefore, transformation and upgrading, pragmatic innovation, so that polyurethane rigid foam can meet the various indicators required by national and local standards, is our business in rigid polyurethane foam for construction Problems that companies solve together.
3. Products developed
The WL-718, WL-616, and WL-516 series of flame-retardant polyols developed and produced by Weilin Co., Ltd. are based on the introduction of a nitrogen-phosphorus flame-retardant structure with a cyanide ring and a benzene ring structure modified by boron and zirconium . (The phenolic hydroxyl group on the benzene ring reacts with boron and zirconium elements to form a boron and zirconium modified ablation-resistant and flame-resistant structure) organically combined and synergistic to achieve flame-retardant effects.

4. Performance indicators
WL-718 is a super flame-retardant polyether (separately foamed) with an oxygen index above 36 (after several verification tests) and can be used in any combination with ordinary polyether and polyester to improve flame-retardant performance , WL-616 oxygen index is 30-33 (combined material), WL-516 oxygen index is 26-28, the above several reactive structure flame retardant polyols, the advantage is that the polyol itself can not only foam but also flame retardant, double The effect is one. The foam produced has high oxygen index, good flame retardancy and high expansion ratio.

V. Application Status
Several products such as WL-718, WL-616, WL-516 have been used by users, and have played an obvious flame-retardant advantage in the application fields of spray coating, continuous sheet, and cold storage materials.
