Platinum polyaddition cure silicone rubber mold making

Brand:aa

Product detail:

 

INTRODUCTION

 

Two component room temperature poly addition curing fluid compound which cures with low shrinkage to a strong flexible mould rubber, it has high temperature and chemcal resistance making it well suited for repducing models with undercuts in polyurethane and epoxy resins..

 

Main field of application

 

Vacuum casting Rapid prototyping

Electrical application

Mould making

  

Special Characteristics:

 

lDifferent Shore A Hardness available from 28-45

lFast and non shrink cure at room temperature which could can be accelerate considerable by  the application of heat

lGood transparency of the cured rubber

lHigh tear strength

lreproduce finite details from patterns

  

TECHNICAL PROPERTIE

 

Appearance (component A)                           : Translucent             Component B (Hardner) : clear liquid

Viscosity (cps)                                               : 85000(at +23°C)                         800

Mixing ratio (mould rubberA+B Harder)          : 10 : 1 parts in weight

Work Time(at + 23°C)                                   : 60 to 90 minutes

Demoulding time (at +23°C)                          : 20 to 24 hours

Specific gravity                                              : 1.220 (at + 23°C))

Hardness (Shore A) At 2mm cured                : 40

Tensile Strength kg/cm²(MPA)                       : 10       

Tear strength kgf / cm ( KN/M)                    : 14

 

Higher temperature and humidity will increase the cure rates and, therefore, reduce work time, lower temperature or humidity will slow the cure time.in standard cured time, the demolding time is 12-24hours. The mold can be used after 48 hours of cure
