After mixing, compounds were removed from the mixer chamber in the form of solids and molded by compression molding in a heated hydraulic press to optimum cure
parameters (90% of the maximum cure--obtained by rheometrical curves) at 177[degrees]C.
Approximately 2 mm sheets were drawn out from the mills and the optimum cure
time ([t.sub.90]) was determined using a rotorless rheometer.
The control allows specific cure profiles for Flogas's different cylinder sizes, allowing each cylinder to have the optimum cure
with the most efficient settings.
From these data, it is clear that the prepared homopolymers and copolymers had an accelerating effect as shown from the decrease in the optimum cure
time and the increase in cure rate index.
But optimum cure
time of reclaim rubber containing compound is slightly superior to those of NR/CB vulcanizate.
Uniform cure of thick rubber articles to optimum cure
is virtually impossible.
Schulman has developed a novel resin modification that reportedly brings the melt to an optimum cure
in a shorter time than can be achieved by modifying molds or machinery.
With exposure to typical commercial UV energy dosages, optimum cure
can be achieved with little or no photoinitiator, according to the company.
The use of a saturation index, Langlier or Hamilton, is mandatory in achieving the condition for optimum cure
for a plastered pool.
Cure characteristics, for example, scorch time ([t.sub.s]2), optimum cure
time ([t.sub.c]90), minimum torque ([M.sub.L]), and maximum torque (Mh) were investigated using a Moving Die Rheometer (MDR, TechPro, Cuyahoga Falls, OH) at 160[degrees]C following ISO 6502.
It means their optimum cure
time, t90, was the same.
Enclosed reflectors can be specifically designed for optimum cure
of complex 3D parts, ensuring full surface cure by creating multiple reflections to maximize energy absorption.
