Rosin filter bag high-efficiency filtration solution to help pure production
In the fields of rosin processing, resin purification and high-temperature viscous fluid filtration, traditional filter materials often affect efficiency due to problems such as blockage and insufficient temperature resistance. With its high temperature resistance, anti-adhesion and high-precision filtration characteristics, rosin filter bagshave become an ideal choice for customers in the chemical, food, pharmaceutical and other industries. We focus on providing high-performance rosin filter bags to customers around the world to ensure your production process is efficient and stable.
Why choose a special filter bag for rosin?
1. Excellent high temperature resistance
Wide operating temperature range: can withstand extreme temperatures from **-40°C to 260°C, and is suitable for harsh environments such as rosin melting and high-temperature resin filtration.
Strong thermal stability: fiber material treated with special processes, does not shrink or deform at high temperatures, ensuring long-term filtration accuracy.
2. Anti-adhesion surface treatment
Low-viscosity coating technology: The surface of the filter bag is subjected to anti-adhesion modification, which significantly reduces the residue of sticky substances such as rosin and resin, and extends the service life.
Easy-to-clean design: supports high-pressure backblowing or chemical cleaning, with high reuse rate and reduced overall cost.
3. Accurate hierarchical filtering
Multi-level accuracy is optional: filtration accuracy from 1μm to 200μm, meeting the entire process needs of coarse filtration, fine filtration to ultra-fine filtration.
High pollution capacity: multi-layer gradient structure design, improve pollution absorption and reduce frequent replacement frequency.
4. Excellent chemical compatibility
It is resistant to strong acids, strong alkalis and organic solvents (such as acetone and ethanol), and is widely used in deep processing of rosin and purification of petroleum resins.

FAQ
Q: What is the difference between rosin filter bags and traditional filter cloths?
A: The rosin filter bag adopts high-temperature fiber + anti-adhesive coating, specially designed for viscous media, with anti-blocking performance increased by more than 50% and a life span of 3-5 times.
Q: Will the filter bag release harmful substances at high temperatures?
A: Our food-grade filter bags have passed FDA certification and are free of toxic substances precipitated within 260°C. They are safe and suitable for food and drug production.
Q: How to judge the filter bag replacement cycle?
A: It can be replaced by pressure differential monitoring (recommended pressure differential ≤0.3MPa) or when the flow rate drops by 15%. We provide free working condition evaluation services.
