PP Versus ABS Protective Cases
PP wins on chemical resistance, low-temperature toughness and cost per unit of impact performance, which is why it accounts for the majority of the KeXin range. ABS wins on panel stiffness, surface finish and print quality, which is why it is preferred where a case is a brand-facing product.
Key points
- Ninety-four KeXin models are PP, thirty-eight are an engineering PP blend, twenty-two are ABS.
- Cold-temperature impact behaviour is the clearest practical difference between the two.
- ABS takes a printed and embossed finish better, which matters for retail-facing cases.
- Wall thickness is a design choice, so a thick ABS case can outperform a thin PP one and vice versa.
Side-by-side
| Property | Pp | Abs |
|---|---|---|
| Low-temperature impact | Retains toughness | Becomes more brittle |
| Chemical resistance | Very good with fuels and solvents | Attacked by some solvents |
| Panel stiffness | Lower, flexes and recovers | Higher, holds shape |
| Surface and print finish | Good | Better |
| Ultraviolet exposure | Requires pigmentation | Chalks and yellows |
| Cost per unit | Generally lower | Generally higher |
How to choose in one question
Ask what the case will be exposed to rather than what it will be dropped onto. A case that lives in a vehicle in winter, or is cleaned with solvents, is a PP case. A case that sits on a shop floor and carries a printed brand is an ABS case.
Applications
This matters most where the case is part of a movement chain rather than shelf packaging. In outdoor & recreation and military the same shell is specified differently because the handling, the environment and the verification requirement differ.

Customisation
Everything described above is configurable on a standard shell: interior layout (pick-and-pluck, die-cut or CNC-cut), foam grade and thickness, colour, logo method, latch and lock count, pressure-equalisation valve, cable ports, document holder and identification plate. A bespoke exterior geometry requires a new mould — 125 days, from 3,000 units per moulded component.
Procurement considerations
| Question | What to send us |
|---|---|
| Which shell fits? | Equipment L × W × H as packed, plus required clearance per axis |
| What does it cost? | Order quantity and estimated annual quantity — the two drive different answers |
| Is tooling needed? | Whether an existing shell clears the envelope with usable foam depth |
| Lead time? | Your required delivery date, not just the order date |
| Certification? | The exact standard your tender names — we will say whether we can test to it |
| Freight? | Destination and preferred terms; carton and pallet data supplied with the quotation |
Comparison and selection guide
The tables on this page exist because a protective case is chosen by comparing three things: the envelope, the environment and the handling chain. Where no table applies, the rule below is.
| Situation | What To Do |
|---|---|
| Start from the equipment, not the case | Measure the tallest, widest and longest points of the packed equipment including antennas, handles and connectors. Add 20 mm minimum clearance per axis before selecting a shell. |
| Then choose the carrying method | Under 8 kg, a fixed handle is lighter and cheaper. Over 12 kg or any journey over 30 m, specify the T series with telescopic handle and wheels. |
| Then decide the interior | Pick-and-pluck for kits that change. Die-cut or CNC-cut for fixed layouts that must be auditable at a glance. |
- Size on internal dimensions plus clearance, never on a product name.
- Choose the carrying method before the shell: it changes the series, not just the price.
- Specify the interior last, and decide up front whether the end user will reconfigure it.
