Biodegradation Additive

Anaerobic Decomposition

This biodegradation additive is offered as a masterbatch to transform non-biodegradable products into biodegradable ones. This product allows for a controlled rate of decomposition through a multi-step chemical process that ultimately results in byproducts of methane and carbon dioxide. The technology converts traditional plastics into a consumable form that can then be broken down by bacteria in the soil (into carbon dioxide, water, and humus).

A key drawback to compostable products is their short shelf life. With the use of our product, polymers have the benefit of a long shelf life that traditional single-use plastics have, but also be able to break down in a much shorter period of time (3 – 10 years versus hundreds of years). All the well-understood properties of polyolefins, polyesters and nylons are retained while also providing the added benefit of biodegradability.

Calcium Carbonate Concentrate

Calcium Carbonate Concentrate

These pelletized mineral concentrates contain up to 80% of a fine-ground, surface-treated calcium carbonate (CaCO3) combined with various polyolefin carrier resins. Composed of FDA-compliant materials, they are designed to improve the performance of polyethylene film, and sheet and coating applications. This high-quality CaCO3 allows for a greater percentage of filler in the resin compound thereby reducing costs, resulting in substantial savings vs. resin.

Key advantages include higher production rates; thermal properties modification; better extrudate stability; enhanced extrusion output due to easier output handling and converting; increased stiffness and impact strength; increased tear strength of LLDPE films; COF modification for easier converting and performance; improved printability, adhesion and seals strength.

Film Heat Seal Modifier

HSIT Modifier

This modifier can be used to modify the initiation temperatures for film sealing. The product’s lower melting point and melting point distribution result in increased low-temperature drawing and dimensional stability. Blending this material into the core layer of films helps to achieve an improvement in heat sealability, processability, softness and optical properties (transparency and gloss).

Target heat seal strength can be achieved at lower temperatures using this material, making it possible to design ultra low temperature processes, leading to cost reduction and line speed efficiency. On the flip side, for low temperature system constraints, a higher heat seal can be achieved through use of this material.

Impact Modifier

Various

We offer impact modifiers for both polyolefins and polyamides, supporting impact strength even at low temperatures. Resin modifiers for polyolefins can improve the toughness, impact and heat resistance of the polymer, and transparency of the final compound. With lower density, lower modulus and lower melting point vs. traditional polyolefins, these modifiers can be used to modify impact and softness in finished compounds. Acid-modified elastomers, with grades based in POE or EPDM, are well dispersed throughout nylon resin to prevent cracking and improve the durability of the polymer. Suitable for both filled and neat polyamide resins.
