| Sponge Roller Type | Advantages | Disadvantages |
|---|---|---|
| PVA Sponge Roller | - Excellent water absorption – ideal for moisture-sensitive applications - Soft texture – gentle on delicate surfaces - Good chemical resistance - Lint-free and non-abrasive | - Relatively expensive compared to other sponge materials - Lower mechanical strength – not suitable for heavy-duty use - Can harden when dry and needs rehydration |
| PU Sponge Roller | - High elasticity and flexibility - Good mechanical strength – durable under pressure - Excellent abrasion resistance - Suitable for both wet and dry applications | - Moderate water absorption – not as good as PVA - Can degrade with prolonged UV or chemical exposure - Less soft than PVA – may scratch delicate surfaces |
| PVC Sponge Roller | - Cost-effective and widely available - Resistant to most acids and alkalis - Reasonably durable and lightweight | - Limited flexibility – can crack under pressure - Poor water absorption compared to PVA or PU - Less environmentally friendly – contains chlorine |
| PP Sponge Roller | - Lightweight and highly chemical-resistant - Durable and tough – good for abrasive tasks - Low moisture absorption | - Poor softness – not ideal for delicate surfaces - Less water-absorbent - Lower elasticity compared to PU |
| EPDM Sponge | - Excellent weather and ozone resistance - Good chemical and temperature resistance - Flexible and durable – suitable for outdoor or harsh environments | - Poor oil and solvent resistance - Less absorbent – not ideal for water pickup applications - Moderate softness – not as gentle as PVA |

PVA sponge is a highly absorbent, soft, and lint-free material widely used in PCB manufacturing equipment. It is especially valued for its exceptional water absorption and retention capabilities, making it ideal for use in drying and cleaning processes during circuit board production. PVA sponge rollers are gentle on delicate surfaces, ensuring that sensitive components on the PCB are not scratched or damaged during handling. Additionally, the sponge’s smooth texture and consistent pore structure help remove contaminants and excess moisture effectively.
PVA sponge is commonly used in applications such as rinsing, water removal, and surface cleaning in automated PCB production lines. The sponge remains stable under various chemical exposures and offers a long service life when properly maintained. Because it hardens when dry and softens quickly when wet, it also provides excellent operational flexibility. Overall, PVA sponge is an essential component in ensuring high-quality, efficient, and reliable PCB processing.
PVA sponge roller is a critical component in PCB manufacturing equipment, known for its superior water absorption, softness, and non-abrasive surface. It is primarily used in cleaning and drying processes, where it effectively removes water and contaminants from the surface of circuit boards without causing any damage. The roller’s uniform pore structure ensures consistent performance, while its gentle texture protects delicate components. PVA sponge rollers also resist most chemicals used in PCB processing, making them durable and reliable for continuous operation in high-precision production environments.
PU sponge roller is commonly used in PCB manufacturing equipment for their excellent durability, flexibility, and resistance to wear. PU sponge offers moderate water absorption, making it suitable for applications that require a balance between moisture handling and surface protection. Its high elasticity allows it to maintain consistent contact with PCB surfaces, ensuring efficient and even processing. Additionally, PU rollers are resistant to abrasion and deformation, which contributes to their long service life and stable performance under continuous operation.
PVC sponge roller is commonly used in PCB (Printed Circuit Board) manufacturing equipment for applications such as cleaning, guiding, and supporting circuit boards during processing. Although not as absorbent as PVA sponge, PVC sponge rollers are lightweight, cost-effective, and resistant to wear and deformation. Their moderate softness helps prevent damage to PCB surfaces while maintaining stability and consistent performance in automated systems. PVC sponge rollers are a practical choice for general-purpose use in PCB handling and processing.
PP sponge roller is commonly used in PCB (Printed Circuit Board) manufacturing equipment for their durability, chemical resistance, and low water absorption. While PP sponge is not as absorbent as PVA sponge, it offers excellent resistance to acids, alkalis, and solvents, making it suitable for harsh chemical environments. Its lightweight and rigid structure also contribute to stable performance and long service life in automated PCB handling systems.
EPDM sponge roller is commonly used in PCB (Printed Circuit Board) manufacturing equipment for their excellent durability, flexibility, and resistance to heat, chemicals, and ozone. While it has lower water absorption compared to PVA sponge, its robust mechanical properties and long service life make it a reliable choice for various stages of PCB production, especially where resilience and stability are critical.
