Industrial products outside the main catalogues, handled with the same discipline as every other line: clear specifications, a COA per lot, and export documentation arranged end to end. The list on this page keeps growing — new products are added as our partnerships deepen. If what you buy today is not listed here, send us the specification — we will tell you whether we can source it, from whom, and at what landed cost.
An aromatic amine and versatile fine-chemical intermediate. Its flagship use is as the core base material of third-generation, metal-free and ash-free gasoline octane boosters — the class that replaced tetraethyl lead and MMT. NMA is rarely dosed neat: blending plants compound it with dimethylaniline, aniline and MTBE into antiknock packages, where 0.1–0.5 wt% in the gasoline pool raises RON by 2–5 numbers. The same molecule serves dye, agrochemical, pharmaceutical-intermediate and rubber-chemical manufacturers.
| Grade | Typical specification | Packing | Typical applications |
|---|---|---|---|
| N-Methylaniline (NMA) | Purity 99.5%; density 0.987–0.989 g/cm³; boiling point 195–196 °C; flash point 83 °C; CAS 100-61-8 | Drum / IBC | Base material of aromatic-amine gasoline octane booster packages for blenders and refineries; intermediate for dyes, agrochemicals, pharmaceuticals and rubber chemicals |
Physical properties above are typical values; the measured values for your lot are issued on the COA. Nitrogen-blanketed packing and storage away from air and light are recommended — the product darkens slowly on air exposure.
Two-component polyurethane-based grouting and foaming systems for underground coal and tunnel operations, tested to the Chinese coal-industry standard MT 113 for flame retardancy and antistatic performance. Mixed 1:1 by volume through a two-piston injection pump, they react in seconds downhole — consolidating broken strata, anchoring bolts and cables, filling goaf areas and sealing noxious-gas zones. Components are supplied in sealed drums with the mixing ratio and pumping equipment data stated on the TDS.
| Grade | Typical specification | Packing | Typical applications |
|---|---|---|---|
| Mining reinforcement Ⅰ (silicate-modified) | Reaction onset 20 ± 5 s and cure 35 ± 10 s (both adjustable); expansion ratio 1–1.2; compressive strength > 40 MPa; non-flammable; resin 1510 ± 50 kg/m³, catalyst 1210 ± 50 kg/m³ | Resin 26 kg drum + catalyst 24 kg drum, mixed 1:1 | Consolidation of loose, broken coal and rock in roadways and working faces — including water-bearing broken strata (no reaction with water); full-length anchoring of bolts and cables; sealing of gas-drainage and water-injection boreholes |
| Mining reinforcement Ⅱ (high-permeability) | Reaction onset 20 ± 5 s and cure 60 ± 5 s (both adjustable); max reaction temperature < 140 °C; expansion ratio > 1.0; compressive > 40 MPa, tensile > 15 MPa, shear > 15 MPa, flexural > 3.0 MPa; flame-retardant & antistatic to MT 113; resin 1050 ± 30 kg/m³, catalyst 1230 ± 30 kg/m³ | Resin 24 kg drum + catalyst 26 kg drum, mixed 1:1 | Low-viscosity grade for fractured coal-rock consolidation — roadway and face reinforcement, advance consolidation of fault and collapse-column zones, and full-length bolt and cable anchoring |
| Mining filling & sealing foam | Expansion ratio ≥ 25×; max reaction temperature < 98 °C; compressive 310 / 210 / 140 kPa at 10 / 50 / 70% strain; flame-retardant & antistatic to MT 113; resin 1230 ± 50 kg/m³, catalyst 1520 ± 50 kg/m³ | Resin 25 kg drum + catalyst 25 kg drum | Goaf-area filling, backfilling behind roadside packs, construction of sealing and fire walls, and rapid sealing of longwall top / bottom corners and noxious-gas zones |
Values are from laboratory sample tests and may vary with downhole conditions; the measured data for your batch are issued on the COA. Components are stored sealed at 15–25 °C, dry and away from heat; resin and catalyst must not be mixed until pumping.
Products outside the twelve main lines are handled case by case. Send the product, the specification and the packing you are buying in China today — we will confirm whether we can source it, from whom, and at what landed cost, with the same document set as every other line.
We will come back with an equivalent, a landed price and a lead time.
