2] as a blowing agent into PUR foams; and FipurTec technology, which eliminates the need for fiberglass mat in SRIM
process is still under development, and various schemes of molds with different geometry, positions of gates, and packages of reinforcing mats are being tested.
Additional advantages of SRIM
compared to RRIM are: (a) SRIM
can easily exceed the maximum content of reinforcing materials for RRIM (less than 25 wt%) because there is no need to pump reinforcing materials into the mold; glass fiber loadings of over 60 wt% in the SRIM
have been reported by Gonzalez et al.
In the SRIM
process, the reaction system starts at a low viscosity.
Focal Project 2 was initiated in 1993 with the goal of demonstrating the manufacture of a large SRIM
part, at a volume of 50,000 per year, that would have a 25% mass reduction over steel and be cost competitive to a comparable steel part.

Features: Chops glass or other fibers at the mixhead; wets fibers with foam mix-inside mixhead; robotic traversing mechanism dispenses foam mix into an open mold.
was a winner of the Transportation Award for the GMT-800 composite pick-up truck box.
The Newton plant also is working on some important advanced SRIM
Turnkey systems include Inter Wet technology for coinjection of fiberglass reinforcement or fillers in the mixhead; CannOxide for the production of liquid carbon-dioxide-blown molded foams; CarDio for liquid-carbon-dioxide blown slabstock foams; Duotec for low-density SRIM
and RRIM door panels; Zero-Time Change fixtures, drum units.
The weight-cutting SRIM
cargo box offers long-term durability, low maintenance costs, including freedom from rust and dents, and excellent hot-temperature and cold-temperature stability.
