I may be wrong, but it looks to me like you are still locked into using Ivoclar's acrylic, which comes in it's own individual "predosed" capsules. But, there are some choices among the types of Ivoclar acrylics:
IvoBase® Material
The best of two techniques
The quality advantages of a heat-curing polymer have been
combined with the processing benefits of a cold-curing
polymer to produce a new PMMA system.
In terms of its chemistry, IvoBase Material is classified as a
cold-curing polymer. However, the quality of the material
is equivalent to and even exceeds that of heat-curing
polymers.
Two different types of material:
IvoBase Hybrid is characterized by its short processing
times. Within 35 minutes, the material thoroughly cures in
the IvoBase Injector. The product is suitable for fabricating all
kinds of removable dentures.
High fracture toughness is the outstanding characteristic
of IvoBase High Impact. The material polymerizes in 50
minutes. It is suitable for the fabrication of structures that
are exposed to heavy loading.
Predosed. Contact-free. Clean.
The predosed capsules always contain the correct amount of
material. Both containers are opened, the monomer is added
to the polymer and then the two components are mixed. In
the process, the skin never comes in direct contact with the
monomer. For health’s sake.
Wide selection of colours
Seven colours are available: Pink, Pink-V and Preference,
Pink-V Implant and Preference Implant (both featuring high
masking ability) and two special colours, 34-V and Clear.
