REGITEX TRH-70 |
| |
 REGITEX TRH-70 is high-concentration natural rubber latex developed by our company.
Currently, mainstream commercial products of natural rubber latexes are concentration of 61%, which are widely used mainly for molding products including gloves, balloons and foam rubber, as well as for adhesives.
Also, products with concentration of up to about 68% are commercialized by means of evaporation method and creaming method to particularly improve drying property.
However, latexes made by evaporation method are poor in drying property despite of the high concentration, because of potassium hydroxide and soap used in the manufacturing process. Also, dried coating films of these products show drawbacks including decreased strength and increased moisture absorbency.
Latexes made by creaming method show progressive creaming during long-term storage due to residual creaming agent used in the manufacturing process, leading to increased concentration in upper layer and decreased concentration in lower layer to cause troubles.
REGITEX TRH-70 was developed to overcome these drawbacks.
TRH-70 is manufactured by an evaporation method with the use of special manufacturing equipment.
