Features:
RH6250 has the characteristics of high transparency, high strength,
good resilience, small deformation value, yellowing resistance and
aging resistance. It meets US FDZ CFR 21. Part. 177. 2600 and
European EN14350-2, Section 4.9 Volatile Compound Test Standards
and European ROHS and REACH Standards. The Pot-life of the mixture
of the two components (closed vessel) at 20°C is 5 days. Increased
temperature reduce the pot-life.
Application:
Suitable for the production of food grade products such as baby
pacifiers, baby bottles, bottle tableware, baby toys, series
products, etc.

Advantages
1) Environmental protection/non-toxicity, FDA food grade silicone
2) High viscosity, not easy to penetrate
3) Can set color (multi-layer color), do not fall off when set
color, pattern is not single, can form different patterns, silicone
printing trend leads the fashion field.
4) Various effects can be printed (bright or matte, round or
right-angled effect, thick or thin, large or small patterns),
strong stereoscopic effect, soft handle and strong adhesion.
5) High wear resistance, brightness and wash-ability
6) Can firmly adhere to the surface of textiles, non-woven fabrics,
dermis, imitation leather and other materials.
7) The effect of wool pressing is good.
8) Solve the problem of firmness of leather and waterproof fabric
effectively
9) Printing gloves, clothing, paper, sports goods, etc., cold and
heat resistance, skid resistance, silk-printed patterns have a
strong three-dimensional feel, and feel soft, and complement each
other with textiles or leather goods; silk-printed patterns also
have excellent peeling strength, wear resistance, brightness; it
also has water-proof, skid-proof, breathable, high resistance, low
temperature. And good leveling.
10) Super elasticity, in the normal range of elasticity of the
fabric does not fall off, cracking. Printing patterns do not
decolor, do not re-dye (not sublimate).
11) Good air permeability, outside water, oil and other pollutants
can not enter, while the inside of the hot air can be permeable.
