The United Kingdom may be better known for tea and technology exports, but let me tell you — it also boasts some world-class silicone manufacturers. Whether it’s medical-grade tubing, automotive gaskets, or custom silicone kitchenware, the UK market demands high standards and traceability. I’ve worked with several British clients over the years, and if there’s one thing I’ve learned — they want quality, compliance, and clarity. No nonsense.
So, here’s my personally curated list of the Top 10 Silicone Manufacturers in the UK. And yes, Ruiyang Silicone (that’s us) makes the list too — because we’ve become a go-to partner for British brands looking for cost-effective, custom silicone manufacturing without sacrificing quality.
1. Primasil Silicones Ltd. – Precision in Medical and Industrial Silicone
Based in Herefordshire, Primasil is one of the UK’s most respected silicone processors. They specialize in medical-grade silicone extrusion and molding, serving industries like healthcare, defense, and electronics.
They offer a full suite of services — from material development to finished silicone parts — and have an especially strong reputation in the implantable and biocompatible silicone space.
2. Silicone Engineering Ltd.
Located in Blackburn, Silicone Engineering is a powerhouse when it comes to silicone sheeting, rolls, and sponge extrusions. Their brands like kSil™, RubaSil™, and ExpanSil™ are staples across industries from automotive to aerospace.
They’re also big on fire-retardant and high-temperature silicones, which makes them a go-to for clients needing EN 45545 and UL standards.
3. Ruiyang Silicone – Trusted OEM Partner for British Brands
Yes — we’re based in China, but we’ve built strong partnerships with UK clients who need reliable, fully customized silicone products at scale. We’ve supplied British brands with:
- FDA & LFGB-certified silicone baby products
- Silicone baking molds and utensils
- Custom-branded promotional silicone items
- Industrial gaskets and molded parts
UK customers love our fast tooling, consistent quality, and export know-how. We’ve helped many British SMEs launch or expand product lines with private label packaging and custom silicone design services.
And we’re no strangers to UK certifications and labeling standards, which makes things smooth when importing.
4. TRP Polymer Solutions
TRP, based in Hereford, specializes in high-performance silicone and rubber components for harsh environments. Their silicone elastomers are used in aerospace, oil & gas, and defense — sectors where failure is not an option.
They also excel in bespoke molded parts with unusual tolerances and dual-material bonding.
5. Silclear Ltd.
Silclear, based in Hampshire, is a niche but high-quality supplier of medical and dairy-grade silicone tubing and connectors. They’re one of the few UK companies that handle short-run production for highly regulated industries, including veterinary and neonatal healthcare.
Their in-house extrusion lines allow for custom inner/outer diameters and wall thickness — a huge plus for clients with non-standard requirements.
6. VFM Medical
Though smaller in size, VFM Medical, based in Manchester, is specialized in custom silicone catheters and implants. They serve OEMs building urology, cardiology, and ENT devices.
They offer cleanroom molding and low-volume prototyping, which makes them ideal for early-stage medical device companies or clinical trials.
7. Techsil Ltd.
Techsil is more of a distributor and solution provider than a manufacturer, but they stock and convert a huge range of silicone adhesives, sealants, and mold-making compounds. If you’re looking for Dow, Momentive, or Elkem silicones in the UK, chances are Techsil is your gateway.
They also offer custom cut-to-shape silicone gaskets and parts for rapid prototyping.
8. Elkem Silicones UK Ltd.
The UK branch of Elkem (formerly Bluestar Silicones), located in Wigan, serves British clients with medical, industrial, and cosmetic-grade silicones. Their Silbione® range is particularly trusted in the healthcare space.
They also offer local technical support and warehousing, which ensures faster delivery and easier compliance for British buyers.
9. Silicone Altimex Ltd. (Part of Avantor Group)
Operating out of Nottingham, Silicone Altimex specializes in cleanroom extrusion and molding for biopharmaceutical silicone tubing and assemblies. Their products are used in sterile fluid transfer systems, vaccine production, and lab-grade disposables.
They’re ISO 13485 and FDA compliant, which makes them a top pick for regulated life science applications.
10. Advanced Materials Ltd.
Based in Manchester, Advanced Materials supplies custom silicone formulations and gaskets for industrial applications. Their edge? They combine chemical expertise with in-house conversion of silicone sheets, foams, and adhesives.
They’re popular among electrical, marine, and lighting manufacturers needing bespoke insulation or weatherproofing parts.
Final Thoughts
The UK silicone market is packed with quality and specialization. Whether you need a medical-grade silicone tube, a flame-retardant gasket, or a beautifully molded cake mold, these ten companies represent the best Britain has to offer.
And if you’re looking to combine British design standards with cost-effective offshore manufacturing, Ruiyang Silicone is here to help. Cheers!
