Smallest Cells = Greatest Benefits

TecoCell® technology produces the smallest cell size achievable (50 – 200 microns) through the exclusive use of nano-sized, (<=0.08 micron) CaCO3 particles.

TecoCell®’s cell size and uniform distribution result in superior mechanical properties and surface appearance compared to conventional chemical forming agents.

Cleaner, Greener Chemistry

TecoCell® chemistry is a cleaner process. All ingredients in the TecoCell® formulation and their reaction products are environmentally friendly. CO2, water and citric salts, all inert and benign, are the only by-products. In contrast, traditional chemical foaming agents produce hazardous by-products that can corrode molds and are environmentally harmful.

The Science Behind TecoCell®

TecoCell®, which is produced through a specialized and patented process, creates a homogeneous gas/cell matrix by utilizing uniform size CaCO3 particles of .08 microns.

The CaCO3 nanoparticles distribute themselves evenly in the material system, resulting in a strong and constant cell structure throughout the blow molded or injection molded part. The uniformity of the cell gives the user a lightweight part with low warpage, faster cycles times, better stiffness and higher heat distortion properties.

This even distribution and small cell size of the TecoCell® additive is especially effective in unfilled PP and PE materials. These materials are commonly used for blow molded automotive ducts and injection molded thin-wall packaging.

TecoCell® for Injection Molding

TecoCell® H1 is a chemical foaming and nucleation system targeted for use with polyolefin and polystyrene materials to provide assistance to the injection molding process with attributes including:

• Premium surface finish

• Lower melt viscosity

• Faster cycle times

• Lighter parts

• Lower clamping pressures

• Lower molded-in stress

• Better dimensional stability

• Elimination of sink marks

• Elimination of voids in thick sections

• Larger process window

TecoCell® H1

TecoCell® H1​​ is a specially formulated concentrate that is recommended for foaming polyolefins and polystyrene, and, nucleation of these polymers when foamed with physical blowing agents. This product activates at temperatures above 400 ̊F. The product is targeted for applications where the smallest cell size achievable with a CFA is required. ​Click here for the TecoCell® H1 Product Information.

TecoCell® Chemical Foaming Agents

• Cleaner chemistry. No damage to the mold.

• Longer shelf-life due to the use of a hydrophobic coating.

• Single reaction temperature leads to greater process control and reproducibility.

• Patented nanoscale grind size which results in a uniformly distributed microcellular structure for achieving greater dimensional stability and aesthetics of molded part.

Competitive Chemical Foaming Agents

• Many CFAs in the market give corrosive reaction by products detrimental to the environment and harsh on the mold surface.

• Leading endothermic CFAs entail a hygroscopic component which decreases shelf-life and product reproducibility.

• Broad distribution of cell size leading to localized non-uniformities in the molded part.
