Choosing the right Gel box

Megapack™ Gel boxes come in a range of shapes, sizes and materials that make them suitable for a range of applications. This guide provides information useful when choosing your box, but if you are unsure or require more information then please get in touch.

Material types

Transparent

VIEW PRODUCTS

Injection-moulded high-impact polystyrene boxes that are completely clear in appearance.


This product is classified as insulate and should not be used where EDS protection is required, or where devices carried are sensitive to the build-up of electrical charge.

Black Conductive

VIEW PRODUCTS

Electrically conductive (ASTM 0-257-78), semiconductor-grade injection-moulded polypropylene boxes that are pre-mixed with pure carbon powder and solid black in appearance.


Surface resistivity < 10-5 ohms/sq

Volume resistivity < 100 ohm - cm

Static delay time < 10 seconds

Black Static Dissipative

VIEW PRODUCTS

Electrically dissipative (ASTM 0-257-78), semiconductor-grade injection-moulded polypropylene boxes that are pre-mixed with pure carbon powder and solid black in appearance.


Surface resistivity < 10-9 ohms/sq

Black/Clear Anti-static

VIEW PRODUCTS

Semiconductor-grade injection-moulded boxes that have a mix of solid black bases and transparent covers.


Base

Same material as Black Conductive.


Cover

Proprietary polymer with non-blooming anti-static properties. Semi-transparent in appearance and classed as static dissipative (ASTM 0-257-78). Surface resistivity < 10-10 ohms/sq.

Tack levels

To hold the content of the Gel box in place securely, we offer three standard levels of retention:

Low

VIEW PRODUCTS

Surface hardness

50 Shore A Scale


Peel force

3 grams

(ASTM D3330/D3330M-04)

Medium

VIEW PRODUCTS

Surface hardness

60-80 Shore 00 Scale


Peel force

6-7 grams

(ASTM D3330/D3330M-04)

High

VIEW PRODUCTS

Surface hardness

48-56 Shore 00 Scale


Peel force

18-20 grams

(ASTM D3330/D3330M-04)

If you are unsure which tack level is right for your products, please contact us for a free sample.

Properties

The gel material used in our Gel boxes is a non-silicone elastomer, which means it will not inhibit soldering, eutectic bonding or gluing. Components requiring any of these production steps can therefore be placed on the gel without the possibility of inhibition. Outgassing and ion contamination tests carried out by customers indicate that the material exhibits very low outgas and very low ionic contamination.


The material has a surface resistivity of 10-12 ohms/sq at 20°C and 40 RH, which means it is described as "insulative" according to ASTM 0-257-78.
