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.

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

10 years ago, when Ms. Waner and Ms. Lynn traveled to some countries, they found that the environmentally friendly polyurethane raw material is not widely used for gyms, playgrounds and running track .By that time the material were already very common in China and they are safe and healthy . As two Chinese women with lofty ideals who care about child safety and human health, Ms. Waner and Ms. Lynn founded Joyway industrial company in 2012. Initially, we provided rubber floor tiles, rubber roll and raw material for running track to foreign customers. Our founding concept has been approved by customers. We can't forget the smiles of children on the playground which was installed with our products. We can not forget the fitness experts sweating like rain on the gym which was made of our material. We can not forget the young voices on the running track installed by our team.

During 5 years of development, we decided to expand our products to provide quality services to more people. In mines industry,

focused on the research, development, manufacturing, and sales of polyurethane screen mesh. Equipped with advanced production facilities and a professional technical team, we are committed to providing high-quality screening solutions to our clients. 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 Tufflex Screen (TPU wire mesh).

In households, we provide ergonomic mattresses, pillows, and other products that coexist with comfort and elegance. It improves the sleep quality of customers who use our products. We brings a better life to customers by our effort.

In order to provide customers high quality products with competitive price, we established PU raw material manufacturing base and we have our own R&D center to customize different formulation upon customer’s requirement . Now our PU raw material system include polyurethane prepolymer, polyurethane rigid PU foam system, polyurethane flexible PU foam system, polyurethane binder,thermal polyurethane , and some upstream materials like polyether polyol, polyester polyol and MDI, TDI.

As our team grows, since 2018, our product range continues to expand upstream and downstream. Now we can provide total solutions for playgrounds and running track and total solutions for polyurethane products. No matter how we develop, our concept is always safety, environmental protection and health. Hopefully our story with you will continue forever !
