What Types of Additive Masterbatches and Custom Formulations Does Polyvel Offer?

Polyvel Inc. supplies specialty additive masterbatches and custom compounds, and its technical team develops custom formulations and loadings to fit a customer's process and product. The company states that its equipment designs allow for all levels of product addition as well as broad resin selections, so the practical answer is: Polyvel's offering spans proprietary additive masterbatches, custom formulations, full compounds, and toll/contract compounding rather than a single fixed product line.

Proprietary Additive Masterbatches

Polyvel describes its masterbatches as proprietary and says they "provide the functional additives and loading characteristics for all your product needs." Two things matter when judging fit:

• Function — the additive is chosen for the property you need in the finished part.
• Loading — the concentration of additive in the masterbatch carrier, which determines how much you let down into your resin.

Because the site does not publish a named product catalog or additive-by-additive data, the specific chemistry and loading ranges are not listed on the page. For a given application, the additive type and let-down ratio are the two questions to put to Polyvel directly.

Custom Formulations and Loadings

If a standard masterbatch does not match your resin, processing window, or target property, Polyvel's technical team develops custom formulations and loadings. The stated purpose is "flexibility in the customers' processes and products" — meaning the formulation is adjusted to how you run the line, not the other way around.

This is the relevant path when, for example, your resin system, filler level, or downstream equipment constrains what a standard grade can do.

Full Compounds and Toll/Contract Compounding

Polyvel notes that its additive masterbatch "can also be manufactured as a full compound." That distinction matters:

Polyvel also offers toll and contract compounding, describing itself as "a fully capable toller." The company says these arrangements can include capital additions and capacity allocation for the customer relationship, and that its team works to understand each customer's immediate and long-term goals. If you need compounding capacity rather than a purchased masterbatch, this is the relevant service.

Equipment and Resin Flexibility

The site states that Polyvel's equipment designs "allow for all levels of product addition as well as broad resin selections." In practice this is the condition that decides whether a custom loading is feasible for your setup — high or low addition levels, and the resin family you run, both fall inside what the company says it can handle.

Markets Served

Polyvel lists the following markets and industries:

• Recycling
• Flexible packaging
• Rigid packaging
• Medical devices
• Nonwovens
• Film / sheet
• Foamed products
• Injection molding
• Blow molding

If your application falls in one of these areas, that is a reasonable starting point for a conversation; it is not a statement that every additive grade suits every listed market.

How to Decide and Next Step

• If you need a functional additive at a defined loading in a standard resin, start with Polyvel's proprietary masterbatch range.
• If your resin, process, or target property falls outside a standard grade, ask about a custom formulation and loading.
• If you would rather buy the additive already compounded, ask about a full compound.
• If you need compounding capacity, ask about toll/contract compounding.

The site does not publish pricing, minimum order quantities, or a downloadable product list, so those details require direct contact. Polyvel lists its address as 100 Ninth Street, Hammonton, NJ 08037, phone +1 (609) 567-0080, fax +1 (609) 567-9522, and email [email protected]. The company also states its QMS is certified to ISO 9001:2015 (certificate registered by Intertek) and references a Polyvel Europe entity.
