Technical Data Sheet

PU-500

(One component Flexible polyurethane foam)

 

1.Where to use

Leakage part of structure having vibration.

The rear disparity of structure.

2.Specific character

PU-500 is one liquid type soft firing urethane having strong hydrophobic type, Through injecting and putting leakage part of structure joint having vibration, It is the product forming water firing stage of open cell structure , keeping elasticity and closing off from Influx water.

Owing to forming high-elasticity at the small amount of water and forming quick response partial gel form at the large amount of water, it is the excellent product having no shrinking change.

3.Basic properties of matter

(Above result can be changed partially by changing the raw material of the product and improvement)

 

Urethane foam.

When we carry out the work on the wet, moisturized site, partially foaming and forms the foaming crystalloid mixed with Urethane and Urea (Carbamide). It is possible for you to order custom-made product and according to the general conditions of the site like temperature, moisture, and the quantity of inflowing water, the reaction time can be decided. Generally, when you are using this company’s high intensity Urethane injection(hardening time 1-2 min) on the site where you are doing the leakage construction with the first step foaming agent(liquid), it will be able to expect simple construction work and shortening the working period simultaneously.

 

4.Packing

A liquid 20kg/iron can container is packed by 20kg/set.

 

5.How to use

Drilling some regular-spaced holes on the cracked part, insert packer and fix it.

Using the grouting injection pump(CP-A800) made by this company, put appropriate PU raw material injection container and do the injection work.

Use the liquid inside the container quickly, if possible. When we use it in the winter season, the viscosity of the medical liquid can rise. In this case, heat the iron can with the hot wind or any other heating gear and descend the viscosity of the medical liquid. Then we can inject easily.
