A good perspective despite reinforcement

The reinforced Grilamid TRV is excellently suited for housings and design components which require a perfect surface quality in addition to high stiffness and strength. Now this product is also available in transparent grades, opening up new applications.

In the form of reinforced grades (Grilamid TRV), the transparent amorphous polyamide Grilamid TR is wellsuited for the manufacture of housings and design components for smartphones or tablets. These components have an increasingly sophisticated filigree and thinnerwalled design which put higher demands on pro-cessing and quality of the materials used. Not only the balance between stiffness and strength is decisive, but also a perfect surface quality. Typical weaknesses of semi-crystalline polyamides are a tendency to warp and formation of sink marks. Surface quality is diminished by the influence of glassfiber reinforcement and shrinkage. Using Grilamid TRV, practically warpagefree, smooth and scratch resistant components with no sink marks and very good surface quality with even the highest degree of reinforcement can be made.

Reinforced and transparent
In the meantime, EMS-GRIVORY has even taken a step further; to date, Grilamid TRV products exhibited loss of transparency due to their fiber reinforcement content. Newly developed grades, Grilamid TRV FE 11078 for example, now make it possible to manufacture transparent, reinforced components with transparency values of up to 90% as well as the advantages of reinforced plastic materials such as higher stiffness and strength. Possible applications for these new Grilamid TRV materials are, for example, housings with directly integrated, lowresolution displays, very stiff filter housings or machine sight glasses with integrated threading.
