Our Product
1. Calender roll base paper (commonly known as 'wool paper'), calender roll
Calender roll base paper (commonly known as 'wool paper') is manufactured on specialised paper machines using a blend of cotton and wool fibres, and serves as a dedicated consumable for calendering, embossing and texturing equipment.
It is widely used in the embossing, texturing and gloss-enhancing processes for materials such as paper, fabric, leather and plastic film.
2. Activated Carbon Filter Paper and Filter Mesh
Specially produced for air purification industry, used for air filtration and purification systems.
3. High-strength cotton pulp
With an appropriate degree of refining and long fibre lengths, it requires only minimal defibration before being fed onto the paper machine; it also enhances the strength and abrasion resistance of the finished paper.
It is primarily used in the manufacture of industrial products such as paper-based friction linings and high-strength paper pulp rolls.
4. PCB Hot Press Cushion Paper for Electronics Industry
This high-temperature resistant cushion paper is specially designed for circuit board hot pressing production.
It can be reused many times without carbonization or blackening under continuous high-temperature pressing conditions.
5. Paper-based brake pad
Paper-based brake pads are manufactured using a wet-forming process, followed by resin impregnation and hot pressing. They are designed for torque transmission and braking under oil-immersed conditions, and are commonly used in automotive, construction machinery and industrial transmission clutch and brake components.
6. Paper-making machinery and equipment
Support services: We sell a wide range of complete paper-making equipment and provide overseas clients with one-stop procurement services, including process design and equipment selection.
Special paper production line
We offer a comprehensive, end-to-end service for speciality paper production lines, covering process design, equipment selection and configuration, installation and commissioning, start-up guidance, and operational maintenance training, to help our clients achieve efficient start-up and production.
7. Anti-static packaging paper: the electronics and semiconductor industries, and other related sectors.
8. Agricultural carbon-enriching fertiliser and mulch film paper: agricultural sectors such as dryland cash crops (the most common) and paddy field cultivation.
9. Fresh meat preservation paper: brick-and-mortar fresh meat shops/market stalls, brick-and-mortar fresh meat shops/market stalls, frozen food processing/meat product factories and other sectors.
10. Automotive filter paper: air filters, oil filters, fuel filters (petrol/diesel), and new applications such as new energy vehicles.
11. Asbestos-free sealing material：sealing of media such as engine oil and coolant.
12. Paper for the cable industry：Power cables (the largest market in terms of volume), control and instrumentation cables, and specialised cables for wind power, etc.
