Two Components Polyurethane Prepolymer For High Rebound Skidding Wheel

High rebound wheel material JYH-85A/B

Two components Polyurethane Pre-polymer for the high rebound skidding wheel

Characteristic: This is two components Polyurethane resin which are used to produce the skate wheel. It enjoys high rebound. It’s normally used to produce the high performance wheels. The color of finished product is milky white.

Hardness: 85A Rebound:85% Casting ratio:100/66

JYH-85B: ISOCYNATE

JYH-85A: Polyol

Casting ratio:

B/A= 100/66

Process temperature:

ISO: 40-50℃

Polyol: 40-50℃

Reactive activation:

By manual: Process temperature, 45℃

Pot life time:3-5min

Machine process:

JYH-85A/B can be processed by the casting machine:

These two components are solid. A component and B component should be melt into liquid at 80-85℃ in the original drum. You can not melt it in an opened drum. After melting, A and B should be poured into the tank totally mix evenly in the tank.

Pls vacuum the ISO and Polyol before casting, Vacuum 40-60min, pressure should be 0-2mmHG.

ISO TANK: Heat to 40-50℃,Vacuum until no bubbles.

Polyol TANK: Vacuum until no bubble at 40-50℃. Then release the gas into atmospheric pressure, mix 10min slowly until the liquid is evenly.

Remark:

1) Seal the tank,add a air drier at the feed inlet, get rid of the moisture. Otherwise the ISO will be reacted with the moisture, and changes to viscosity. It will effect the mechanical performance.

2) The material has to be used up at one time, if can not, the rest materials should be sealed by the dry N2.

3) Materials should be cast by the recommended ratio.

4) Post cure time: 45min at 100-110℃.

Package:

20kg per drum

Storage:

The materials should be stored in the cool dry place, get rid of moisture.

Shelf life:

6 months

Joyway industrial Co.,Ltd. was founded by two great ladies in 2012.

Initially, we made the Polyurethane binder and rubber tiles for the playground and GYM. Because we focused on to provide the environmentally friendly polyurethane raw material for caring the safe and healthy of the children all over the world.

After decades of development and in response to market and customer demands, Joyway Group has expanded its product range and gradually established two specialized production bases focusing on polyurethane resin/ Polyurethane Pre-polymer and Rigid blend Polyols. At the same time, the Group provides partners with upstream and downstream raw materials for polyurethane production. So, currently, the main Polyurethane resin at below.

• Polyurethane Pre-polymer
• Blend Polyols
• Polyether polyols
• TDI (Toluene Diisocyanate)
• Polymeric MDI (Methylene Diphenyl Diisocyanate)
• MOCA (4,4'-Methylene-bis(2-chloroaniline))
• Release agents
• Planetary mixers
• Pu-metal bonding adhesive
• Other additives required for polyurethane products

This comprehensive product portfolio not only meets industry demands but also positions the Group as a key integrated service provider in the polyurethane sector.  

In 2021, in response to the market demand for high-quality polyurethane vibrating screens for mining applications, Joyway Group established a dedicated R&D team. This team focused on multiple aspects, including raw materials, molds, and casting platforms, leveraging its expertise in materials to break international monopolies. The result was the production of Polyurethane fine screens characterized by small aperture mesh sizes, excellent elasticity, long service life, and high cost-effectiveness.

In the same year, Joyway Group Chemical founded its subsidiary, Qinjin Qixing Mining Equipment Co., Ltd., and formed a joint venture with its Indian partners to establish a production base in India. This China-India collaboration aims to broaden perspectives and provide high-quality, durable screening equipment for the mining industry and related sectors.

Additionally, we offer a variety of screening equipment for the mining industry, such as linear screens, banana screens, vibrating screens ect. We are committed to delivering comprehensive screening solutions to our customers!

Currently，Our products are widely used in industries such as mining, coal,aggregates,chemicals and construction.

We have various polyurethane screen panel like Urethane Screen Panel,Polyurethane Tension Screen,Polyurethane Dewatering Screen Panel,Modular Polyurethane Screen,Flip-Flow Screen and TPU wire mesh.

Now, our product range continues to expand upstream and downstream.

In the future.

We have exported products to Europe and other countries in Asia,South America, Africa, Russia etc. Due to our excellent service and professional technical background, we also act as purchasing agent for some customers according to their specific requirements.

No matter how we develop, our concept is always safety, environmental protection and health. Hopefully our story with you will continue forever !
