Corona Nip Roller

Description of Corona Nip Roller

Corona Nip Roller used in pull roll stand of various polyfilm production lines, the corona nip roller works together with the corona roller and pull roll stand cooling roller. Corona nip roller surface coated synthetic rubber or EPDM rubber with good resilience and excellent ozone resistance, anti-static and aging resistant performance, and its roller surface can be machined into the crowing in different values by the numerical control crowned machine as required. The hardness of the synthetic rubber or EPDM generally 55-65 Shore A, after formula processing, the ruber can withstand temperatures up to 130 degrees Celsius.

Corona Nip Roller Specifications

Corona Nip Roller Advantages

(1). Good stability under pressure at elevated temperature.

(2). Good abrasion and tear resistance.

(3). Very good resistance to acid and alkaline products and to ozone.

(4). Moderate resistance to polar solvents - not suited for contact with aromatic solvents - moderate oil resistance.

(5). Good consistent speed, the primary corona nip rollers in the polyfilm production process ensure a consistent speed, which directly affects film quality and profitability.

(6). Good film quality, the flat and smooth surface of the nip rollers prevents defects such as creasing or film damage caused by crushing the folds.

(7). Uniform pressure, the corona nip rollers apply uniform pressure across the film, ensuring consistent and equal roll speed and uniform pressure between the rollers.
