Characteristics
ELASTOSIL
LR 3003/60 US Liquid Silicone Rubber is
a 60 durometer, commercial grade liquid silicone
rubber designed for liquid injection molding.
Special characteristics
ELASTOSIL
LR 3003/60 US was tested according
to the recommendations of the US Pharmacopoeia
and meets the requirements of Class Vl.
ELASTOSIL
LR 3003/60 US contains those
ingredients which are suitable for food contact.
Under Title 21 “Food and Drugs” Part 177.2600, “Rubber articles
intended for repeated use.” because this regulation contains
limitations, compliance to the regulation is the responsibility of the
user

* Properties obtained after mixing Part A and Part B in a ratio of 1:1. *
* Extrusion rate obtained at 90 psi and 0.125 inch orifice ** Pot life determined by
time required for extrusion rate to be reduced to 50% of initial value.
