THE AGONY

WHY YOUR CURRENT SILICONE SUPPLIER
IS COSTING YOU MORE THAN JUST MONEY

Every failed batch, rejected shipment, or compliance issue traces back to one source: the wrong manufacturing partner. If you're losing money, time, or sleep over silicone quality — you're not alone.

Inconsistent Quality & Batch Variation

Inconsistent wall thickness, hardness variation, and surface defects from batch to batch. Cheap silicone fillers degrade performance and shorten service life — costing you rework, downtime, and lost clients.

Certification & Safety Risk

Unverified food-grade or medical-grade claims trigger compliance failures, product recalls, and permanent damage to your brand. Missing traceability documentation makes audits a nightmare.

Long Lead Time & Custom Difficulty

Trading companies add layers, delay communication, and can't produce truly custom parts. 4–6 week lead times on standard sizes, no in-house engineering, and zero flexibility on MOQ.

There is a better way. Haiwang solves all three — with 20 years of proof.

THE SCIENCE · THE HAIWANG STANDARD

GERMAN-STANDARD QUALITY,
ENGINEERED IN CHINA

We don't just claim quality — we engineer every dimension of it. From raw material selection to finished product, here's exactly what makes Haiwang silicone the right choice for both food-grade and industrial applications.

MODULE A · THE MATERIAL

Food-Grade & Industrial-Grade Formulations

Two specialized material grades for distinct applications. Our food-grade silicone complies with FDA and LFGB standards for safe food, beverage, and pharmaceutical contact. Our industrial-grade silicone is engineered for high-temperature sealing, fluid transfer, and heavy-duty environments — both delivered with consistent batch-to-batch quality.

  • Food-grade: FDA 21 CFR 177.2600 & LFGB compliant
  • Industrial-grade: heat-resistant, durable formulations
  • Precise durometer control (Shore A 30–80)

"

We switched from a well-known German silicone tubing brand to Haiwang two years ago. The product quality is indistinguishable — same clarity, same tear strength, same FDA compliance — at literally 40% lower cost. Their engineering team even helped us optimize a custom multi-lumen profile that our old supplier refused to touch.

For our medical device line, certification traceability is non-negotiable. Haiwang provides batch-specific test reports and full material traceability every single time. Their our food-grade silicone consistently passes our biocompatibility testing. Lead times are 2-3 weeks faster than our previous domestic supplier.

We distribute industrial seals across Mexico and Latin America. Haiwang's OEM capability and flexible MOQ have been a game-changer for our private-label line. The foam sealing series in particular has been a strong seller — consistent quality, fast reorders, and their WhatsApp sales team responds within hours, not days.

TECHNICAL FAQ

EVERYTHING YOU NEED TO KNOW

Straight answers to the technical and commercial questions B2B buyers ask us most. Don't see your question here? Chat with an engineer directly.

What's the difference between food-grade and industrial-grade silicone? +

Food-grade silicone is formulated to meet FDA 21 CFR 177.2600 and LFGB standards for safe contact with food, beverages, and pharmaceuticals. It uses higher-purity raw materials and is typically more transparent. Industrial-grade silicone is engineered for heavy-duty applications like high-temperature sealing, fluid transfer, and weatherproofing — it prioritizes durability, compression set resistance, and cost-efficiency over food-contact compliance. Both grades are available in custom sizes and durometers.

Can you produce custom sizes and profiles? What is the minimum ID? +

Yes — custom sizes and profiles are our specialty. We can extrude silicone tubing with inner diameters as small as 0.5 mm and as large as 80 mm. Custom profiles, multi-lumen tubing, and co-extruded dual-color parts are all produced in-house. Custom tooling typically costs $50–$300 USD depending on complexity and is ready in 5–7 working days. We can also produce sample lengths for testing before full production.

What certifications do your food-grade silicone products carry? +

Our food-grade silicone complies with FDA 21 CFR 177.2600, EU LFGB (BfR XV), and RoHS standards. We also offer USP Class VI medical-grade formulations for pharmaceutical and biotech applications. All grades come with batch-specific test reports and full material traceability. We can provide third-party testing reports on request.

What is your typical lead time? +

Standard sizes in stock: 3–5 working days. Custom standard profiles (existing tooling): 7–10 days. New custom tooling + production: 12–18 days (5–7 days for tooling + 7–11 days for production). Expedited options are available — please tell us your deadline and we'll tell you if we can hit it. We ship worldwide via DHL, FedEx, and sea freight depending on order size and urgency.

What is the minimum order quantity (MOQ)? +

For standard stock sizes: as low as 10 meters per size. For custom profiles with existing tooling: typically 50–100 meters depending on cross-section size. For new tooling: 200–500 meters depending on complexity. We understand that new projects need flexibility — we can often arrange small prototype runs at a slightly higher per-unit cost to help you validate before committing to full production. Just ask.

Can silicone tubing handle autoclave sterilization? +

Yes — our food-grade silicone tubing can withstand repeated autoclave cycles at 121°C (250°F) and 15 psi, which is the standard for medical and laboratory applications. Special grades can handle up to 134°C cycles. Silicone maintains its properties for hundreds of autoclave cycles, though gradual change in transparency and slight hardening may occur over extended use. We can provide sterilization compatibility data for your specific application on request.
