S&E Specialty Polymers, being a truly custom compounder, took the same philosophy to the polymer concentrate business. Our current portfolio of concentrates (masterbatches) includes more than 20 formulations, which address most of today’s needs. We are also rapidly expanding into advanced polymer, innovation compounding and the nanotechnologies area.
The goal of concentrates is the ideal dispersion of additives in the polymer matrix. The fine, powdery feed material often tends to agglomerate and therefore is difficult to work with. Concentrates (masterbatches) with an additive share of 20 – 90% are available, depending on the feed material.
Using masterbatch increases the process stability. Additionally, since there is no handling of large powder masses, the environment and the work station remain clean.
S&E’s portfolio of concentrates are divided into five main categories. When more than one additive is required, S&E can combine two or several of these additives to provide multifunctional performance into a single custom concentrate, or the customer can combine them individually themselves when applicable.
- Flame Retardant (FR)
- Ultraviolet (UV)
- Odor Masking
Depending on the application and requirements, our concentrate materbatches can be formulated for extrusion, injection molding and the blow molding processes. Our concentrates will help you to achieve the best distribution and dispersion of additives.
Our widest offering of concentrates contains super high loadings to produce Flame Resistant masterbatches for polyolefins. The latest upgrades to our manufacturing process allow us to produce up to 85% active FR masterbatches. Then, by using as little as 9% of the concentrate into the base resins, we are able to achieve an UL 94 flame rating. These final compound blends are ideal for thin wall wire and cable applications.
Please let us know what your specific needs are and we will design the right polymer concentrate for you.
