Three component Polyurethane Pre-polymer Polyurethane Pre-polymer for the skate wheel

Description

This system materials is three component. P is polyol component, and I is MDI-terminated pre-polymers, C is cat.

Application

This system material is used to produce middle rebound Polyurethane skate wheel.

Characteristic

It has excellent processing properties, cured under room temperature, short demould time, and the color can be changed by adding pigment. The final products are transparent which enjoy good abrasion resistance, water resistance, good resilience. The hardness is 80A.

Characteristics of components & Physical properties

Storage

Store in a cool and dry place,If you can’t use it up at one time, Pls fill nitrogen gas and then seal it.

Shelf life

The storage time of original packing is 6 month at the above condition from the date of production.

Packing

20kg or 200kg per steel drum

Operation by manual

1．Take certain A component and C component as A+ to make reserve.

2. Calculate B component to make reserve.

3. Pour B component to A+ component and stir evenly.

4. Cast the mixture of step 3 to the mould.

6. Open the mould when the product is hard.

7. Post cure 16 hours at 100℃.

Note: The mixture in the step 3 can be vacuumized to get rid of bubble.

Operation by casting machine

1. Put some A component and C component into A tank, vacuumize to make reserve.

2. Put some B component into B tank, vacuumize to make reserve.

3. Cast the two materials according the ratio to the mould.

4. Open the mould when the product is hard.

5. Post cure 16 hours at 100℃.

Safety

Use in a well ventilated area. Avoid contact with skin using protective gloves and protective clothing. Repeated or prolonged contact on the skin may cause an allergic reaction.

Eye protection is extremely important. Always use approved safety glasses or goggles when handling this product.

Never give anything by mouth to an unconscious person.

Note 1

It generally cures to a demouldable state in 30 to 60 minutes; however, thin sections or certain part configurations may require more in-mould cure time. Sections that are less than 3mm may require more before demould. It depends on different products.

Note 2

Both components should be mixed before each use to ensure uniformity of the materials. Opened containers of material should be prevented moisture contamination from humid air.

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 !
