Lh-1640 liquid rubber is a 2-component product formulated for use in liquid injection molding to high performance elastomeric parts.It is clear, but easily pigmentable with masterbatch colors.
The combination of excellent tear strength and very high tensile strength makes this product suitable for a wide variety of applications. and valve parts can be made readily from Lh-1640 liquid silicone rubber. Lh-1640 offer convenient 10:1 mix ratio, high tear strength, and easy release from molds. Other possible application include using screen printer, not using injection, has been developed and applied to textile. It tends to be used as labeling in textiles and coating in cloths and industrial material.

With the increasing consciousness of environment protection, there are strictly restriction on the usage of PVC in the countries in Europe and USA successively. The reason is due to the PVC manufactured products, such as products used for infants, there is a kind of poisonous substance - phosphonate phthalic acid ester in softener. This substance may destroy the kidney, liver and gal, affect the growth and development of endocrine, hormones genital organs of the kids, and even causing cancer after they bit it. Meanwhile, it is difficult to recycle PVC. The handling way for PVC presently used is burning it, which will produce a large quantity of acid poisonous gas to pollute the environment. Thus, the relative industries are now looking for substitutes for it. Under this situation, the label industry is also searching for the substitutes without exception. The Yue Xin Company developed silicon label material, which is green environmental friendly material. The excellent substance nature of this material can solve the problem of PVC harmful to the human body and environment. A large number of physiology experiments, such as taken orally, stimulation on skin and eyes, absorbed by stomach, and metabolic function, etc. confirm that the silica gel is a kind of poisonous material. And the rejected silica gel will become silica, water and carbon dioxide after degraded by water (with nitric acid), clay and ozone when it enters into the environment. It will not give any harmful affect to environment. The silicon label material with both of these advantages will definitely bring constitutional reformation to label Industry.
