半精炼石蜡（50-68°C） — Frequently Asked Questions

The MOQ for semi refined paraffin wax is typically one pallet (approximately 500 kg in 25 kg cartons) to one full container load (15–20 MT). Full container quantities offer the most competitive pricing per tonne. Please contact us to confirm current MOQs for your grade and delivery destination.

Semi refined paraffin wax is typically priced below fully refined grades, reflecting its higher oil content and less intensive refining. Please contact our sales team for current pricing based on your required grade, volume, and delivery terms.

Yes, semi refined paraffin wax is widely used in candle making, particularly for lower-cost taper, pillar, and utility candles. Its residual oil content (1–3%) can produce a slightly softer, less white finish compared to fully refined grades. For premium candle brands, fully refined or microcrystalline blended grades may be preferred.

The congealing point corresponds closely to the stated melting point grade. Needle penetration at 25°C is typically 18–28 (ASTM D1321), slightly higher (softer) than fully refined grades due to residual oil content. Grade-specific values are confirmed in the batch CoA.

Yes, semi refined paraffin wax (typically 1–3% oil, 52–60°C melting point) is used in rubber processing and tyre manufacturing as a processing aid and anti-ozonant. It migrates to the rubber surface, forming a protective layer that inhibits ozone cracking.

Semi refined paraffin wax is available in 25 kg cartons (slab form), 180–200 kg fibre drums, and bulk liquid form for very large volume users. Standard slab in carton is the most common format for B2B supply. Please specify your preferred packaging when enquiring.

Yes, paraffin wax emulsions produced from semi refined paraffin wax are used in textile finishing to impart water repellency, smoothness, and improved handle to fabrics. Direct application or emulsified grades can be supplied depending on the finishing process used.

Semi refined paraffin wax typically has a Saybolt colour of +15 to +25 (off-white to cream, less bright than fully refined) and a mild, petroleum-characteristic odour. Higher oil content grades tend to have more pronounced colour and odour. Values are confirmed in the Certificate of Analysis.

Yes, paraffin wax — both semi refined and fully refined grades — is used in safety match production. Paraffin wax is applied to the match stick as a fuel source, helping sustain combustion after ignition. Please contact us with your specific grade requirements.

Standard documentation includes Certificate of Analysis, Safety Data Sheet (SDS), Certificate of Origin, and where applicable, food contact compliance statements. PAH testing reports are available for food and cosmetic adjacent applications upon request.

The primary difference is oil content: fully refined paraffin wax has ≤0.5% oil (white, low-odour, suitable for food, pharmaceutical, and cosmetic applications), while semi refined has 1–5% residual oil (off-white, mild petroleum odour, suitable for industrial candles, rubber, board coatings, and explosive manufacturing) at a lower cost.

Yes, semi refined paraffin wax is used for wax-impregnating corrugated board and containerboard to provide moisture resistance for produce and seafood packaging, and in cup stock coating. Please contact us with your specific board grade and application requirements.

We source semi refined paraffin wax from Iran, Russia, China, South Korea, and the Middle East (Saudi Arabia, UAE). Origin preference can be specified; availability is subject to current market conditions and trade regulations. Full origin documentation is provided with each shipment.

Yes, semi refined paraffin wax can be further refined or blended with fully refined paraffin wax to reduce oil content for more demanding applications. Custom blending to a defined oil content target is available. Please contact our technical team with your specification requirements.

Lead times from major producing origins (Iran, China, Russia) to Asian markets are typically 2–4 weeks; to African markets, 4–6 weeks depending on destination port. Please contact us for specific port lead time estimates.

Yes, semi refined paraffin wax is used in the explosives industry (in ANFO and other commercial explosive formulations as a fuel component) and in match manufacturing. We can supply appropriate grades with relevant documentation. Please contact us with your specific grade and application requirements.

PAH testing (MOSH/MOAH analysis and PAH4 screening) is available on semi refined paraffin wax for buyers in food-adjacent, cosmetics-adjacent, or regulated applications. Standard industrial grade supply includes CoA without PAH testing unless specifically requested.

Semi refined paraffin wax typically has a kinematic viscosity of 3.0–5.5 cSt at 100°C (ASTM D445). Grades with higher oil content tend to have marginally higher viscosity. Grade-specific viscosity values are provided in the technical data sheet.
