Shop thermal pads and gap fillers for electronics assembly in South Africa. Local stock, branch pickup, VAT invoices and bulk quotes available at Communica.

Check Samrand, Pretoria or Cape Town branch availability and collect locally.
Compare W/mK, thickness and electrical insulation for correct selection.
Pre-cut kits, heatsink combos and VAT-quoted bulk orders available.
Thermal pads are soft, compliant materials used to bridge gaps between heat-generating components (ICs, power modules, MOSFETs) and heatsinks or enclosures. For South African makers, students and procurement teams, choosing the right thermal pad balances thermal conductivity, thickness, compressibility and ease of assembly. This landing page helps you buy thermal pads for electronics assembly with local availability, compatibility guidance and specification callouts.
Communica stocks a range of thermal interface materials across head office and branches. Check stock levels and branch collection options at our Samrand head office or view branch hours online. For large orders, account quotes and VAT invoices are available for education and commercial buyers.
Common pack sizes include sheets, pre-cut pads and rolls. Typical lead times for non-stock items can vary; consult product pages or request a quote for exact delivery estimates in South Africa (ZAR pricing and lead-time estimates supplied on request).

| Type | Thermal Conductivity | Typical Use |
|---|---|---|
| Silicone-based thermal pad | 1.0-6.0 W/mK | General purpose, flexible gaps |
| Phase-change pad | ~1.0-3.0 W/mK | High contact with low clamp force |
| Graphite/metal-filled pad | >6.0 W/mK (varies) | High-performance cooling, watch electrical conductivity |
If you need help matching pad thickness to your assembly, our technical team can help measure gap tolerances and recommend options. For branch pickup and opening hours, see our branch information: Branches & Trading Hours.
Compatibility matters: choose electrically insulating pads near exposed PCB traces, or use thermally conductive but electrically insulating silicone pads when isolation is required. For power modules and high-current components, prefer pads with higher W/mK and sufficient thickness to avoid mechanical stress on solder joints.
Compare specifications before bundling: example bundle could include a 2 mm silicone thermal pad (3 W/mK), a small aluminium heatsink and a 10 g tube of thermal adhesive. Check compatibility on product pages in our collections: Collections.
Basic installation steps:
1) Clean mating surfaces (isopropyl alcohol) 2) Measure gap and select pad thickness 3) Remove protective films and align pad 4) Apply controlled clamp pressure and re-check contact
Troubleshooting common issues: poor contact usually results from incorrect thickness or uneven surfaces. If temperatures remain high, verify pad placement, consider a higher W/mK material, or add mechanical fastening to improve pressure distribution.
