PBT (polybutylene terephthalate) is the engineering polyester behind countless electrical connectors, sensor housings, and automotive components. It combines fast crystallisation and excellent electrical properties with low moisture uptake and good chemical resistance — and unlike polyamide, it keeps its dimensions when the weather changes. NAGOMER supplies PBT stock shapes and machines components for electrical, automotive, and industrial customers.

POM is the most widely used precision engineering plastic, but it comes in two distinct chemistries: homopolymer (POM-H, the original Delrin-type acetal) and copolymer (POM-C). They look identical, machine similarly, and cost about the same — yet they fail differently, and choosing the wrong one quietly shortens part life. This guide explains the real differences and when each belongs in your design.

Plastic screws solve two problems at once: they cannot corrode, and they never create a galvanic couple with the plastic parts they hold. They also behave differently from metal fasteners — torque limits are far lower, thread engagement must be deeper, and thermal expansion changes clamp load. NAGOMER machines PEEK, PVDF, and PA fasteners and threaded components for chemical, medical, and electronics applications.

Joining plastics with adhesives is often cleaner than welding, faster than mechanical fastening, and essential where a sealed joint is required. The difficulty is surface energy: polyolefins and fluoropolymers will not bond to anything without treatment, and even PEEK and POM need preparation to reach full joint strength. This guide covers which plastics bond easily, which need treatment, and how to prepare each.

Tubing is where engineering plastics quietly outperform metal: it will not corrode, it insulates electrically and thermally, and it can be machined, bonded, or flared on site. But wall thickness, pressure rating, and material choice vary enormously between PEEK, PTFE, PVDF, PA, and POM tubing. This guide covers the selection criteria and the applications where each material belongs.

Water treatment plants are hostile to metals: chlorinated, ozonated, saline, and sometimes hot — often all at once. Reverse osmosis, ultrafiltration, and desalination systems increasingly rely on engineering plastics for membrane housings, pump components, valves, and seals. NAGOMER supplies PVDF, PEEK, PTFE, and UHMW-PE components for water systems worldwide.

Plastics move. A 500 mm PEEK component grows by more than a millimetre over a 50°C temperature swing, and UHMW-PE moves several times that. Ignoring thermal expansion is the most common cause of binding assemblies, cracked housings, and seals that leak when hot. This guide gives you the coefficients, the design rules, and the practical fixes for dimensionally critical plastic components.

Choosing a plastic for a medical device is only half the decision — the other half is how it will be sterilised, and how many times. Steam autoclave, gamma irradiation, ethylene oxide, and vapour-phase hydrogen peroxide each attack polymers differently, and a material that excels under one method can fail miserably under another. NAGOMER supplies sterilisation-compatible stock shapes and machined components for medical device manufacturers.

Modern engine bays run hotter, tighter, and more chemically aggressive than ever, yet metal under the hood is steadily being replaced. Glass-filled PA66, PPS, PEEK, and POM now serve in intake systems, pumps, sensors, and transmission components — cutting weight, damping noise, and resisting oils and coolants that attack metals. NAGOMER supplies stock shapes and machined prototypes for automotive development and small-series production.

Ultra-high molecular weight polyethylene (UHMW-PE) is the abrasion champion of engineering plastics — outwearing steel in sliding wear, refusing to absorb water, and sliding with less friction than almost any other material. Its limits are temperature and stiffness. NAGOMER supplies UHMW-PE sheet and rod for conveyor liners, chain guides, and impact pads across food, mining, and logistics operations.
