Why Plastics for Oil & Gas
High-performance polymers outperform metals in corrosive, abrasive, and weight-sensitive environments across the oil and gas value chain.
Corrosion & Chemical Resistance
Resist hydrocarbons, H₂S, seawater, and process chemicals where metals fail.
Non‑Galling & Low Friction
Excellent wear performance in dry and lubricated service without galling.
Electrical Insulation & Non‑Spark
Inherent insulation and non‑sparking characteristics for hazardous zones.
Reduced Weight & Noise
Cut weight and dampen vibration compared to metal counterparts.
Dimensional Stability
Right polymer selection delivers stability under temperature and pressure.
Cost‑Effective Low Volumes
Prototypes, spares, and short runs where molding is not economical.

We work with a wide range of engineering plastics and high‑performance polymers. For oil and gas applications, common options include:
PEEK
Unfilled, glass‑fiber, carbon‑fiber, bearing grades
High strength, high temperature, excellent chemical resistance. Valve seats, back‑up rings, wear components.
PTFE
Virgin and filled: glass, carbon, bronze, graphite
Outstanding chemical resistance and low friction. Seals, seats, wear strips.
PAI (Torlon‑type)
High‑temperature polyamide‑imide
High strength and creep resistance at elevated temperature. Bushings, bearings.
PPS
Polyphenylene sulfide
Strong, chemically resistant, dimensionally stable. Valve parts, precision components.
PEI / ULTEM
Polyetherimide
High temperature and insulation properties. Electrical isolators, structural components.
PPSU / PSU
Polyphenylsulfone / Polysulfone
Hot water and chemical service. Fluid‑handling components.
PVDF
Polyvinylidene fluoride
Strong resistance to chemicals and UV. Valves, pump parts, chemical processing.
POM / Acetal, Nylon, UHMW‑PE
Engineering thermoplastics
Wear parts, guides, low friction components in moderate environments.
PMMA / Acrylic, PC
Transparent polymers
Transparent covers and sight windows within chemical/temperature limits.
Antistatic or conductive grades are available for use in explosive atmospheres. Final compliance should be validated to your equipment certification requirements (e.g., ATEX/IECEx).
Our team helps you select materials based on temperature, chemical exposure (including sour service), pressure, friction, moisture absorption, and dimensional‑stability requirements.
