ElastaPro is one of North America’s largest mixers of silicone rubber because we calender more solid silicone sheeting than any other supplier on the continent. As a silicone manufacturer, our capabilities don’t just benefit customers who buy our sheet materials. We also supply uncured silicone compounds with consistency, reliability, and speed – and it’s backed by our certified AS9100D and ISO 9001:2015 quality system
Today, ElastaPro can deliver most key silicone compounds in just one week, a lead time that provides an advantage to original equipment manufacturers (OEMs), fabricators, and molders who can’t afford production delays. We also offer one-week turnarounds for uncured silicone compounds in any of our standard grades and specifications.
Our quick turnaround is supported by decades of experience in the inventory management of key elastomers, ensuring a strong supply chain so that your orders are on time.
Silicone Mixing and Why It Matters
Silicone mixing is the process of blending raw silicone polymer with reinforcing fillers, pigments, additives, and performance enhancers to create a uniform, ready‑to‑use compound. The goal of mixing is consistency. Every pound of material must cure the same way, deliver the same mechanical properties, and behave predictably in molding, extrusion, calendering, or die‑cutting.
Mixing is where silicone becomes ready for the next step. This physical process determines hardness, tensile strength, elongation, compression set, thermal stability, and color. For industries ranging from aerospace and defense to medical and healthcare, the quality of the mixing process directly affects product performance.
Mixing vs. Compounding vs. Formulation
Mixing and compounding are sometimes used interchangeably, but they are different levels of material development.
- Mixing uses high-shear equipment to ensure a uniform compound.
- Compounding refers to the selection and proportion of ingredients to achieve the material’s specific properties.
ElastaPro has both silicone mixing and compounding capabilities. That’s important because as a silicone compounder, we understand how fillers, additives, and cure systems react – and how to tune them for performance.
We also have silicone formulation capabilities that enable us to design new material systems, create proprietary blends, and solve complex performance challenges. By operating across all three domains – mixing, compounding, and formulation – ElastaPro gives customers a single source for both innovation and production.
Why ElastaPro is Silicone Mixing Leader
ElastaPro’s volume of silicone mixing is directly related to our position as North America’s largest supplier of solid silicone sheet. Calendering requires enormous volumes of uncured compound, and our sheet business runs at a scale few companies can match. That creates the following advantages.
High Volume Mixing Capacity
Our mixing machines run continuously to support sheet production. That requires us to maintain large inventories of base polymers, fillers, and additives. Customers benefit since there’s no waiting for raw materials to arrive before mixing can begin.
Unmatched Consistency
Mixing silicone at an industrial scale requires tight process control. Our sheet customers demand uniformity across thousands of pounds of material, and that same precision applies to every batch of uncured silicone compound that we ship.
One-Week Lead Times
ElastaPro can add custom mixing jobs to our production schedule without significant delay. Whether you need a specification-grade silicone or a flame-retardant formulation that meets UL 94V-0, the lead time is the same: just one week.
Support for Large and Small Orders
Some customers only need 5 pounds of a custom silicone compound. Others need 5,000 pounds instead. Our mixing capabilities can handle both, and with quality and efficiency.
Redundant Equipment
ElastaPro has invested in equipment redundancy. We operate multiple units of the same machines so that if one mixer is unavailable because of maintenance, another takes its place. The same machines provide the same results, regardless of which line produced the batch.
Putting Our Scale to Work for Customers
Because ElastaPro is both a leading silicone sheet producer and a leading silicone mixing company, our customers gain access to a vertically integrated silicone ecosystem. From rapid color matching to tight batch-to-batch consistency, we deliver greater value. If you need uncured silicone compound, we’re ready to provide the right material, at the right time, with the right performance.
