Product description
tesa® 4549 is a tear‑resistant uncoated cloth tape based on a 145 mesh rayon backing with a natural rubber adhesive. The tape is flexible and highly conformable, designed for edge protection, masking and general assembly tasks where adaptation to shaped or uneven surfaces is required. Low unwinding forces make it suitable for automatic dispensing and machine application.

Sustainable Aspects

• 69% bio‑based carbon content (DIN EN 16640)

Product features

• Very conformable: adapts to uneven and formed surfaces without creasing
• Low unwinding force to support automatic dispensing
• Good adhesion on rough and structured substrates
• Writable surface for marking and identification
• Available in black and white; also available on spools

Application fields

• Edge protection of glass panels during production, transport and storage
• Use in leather and textile production (e.g. sewing aid)
• Reinforcement in production of protective wear
• Machine sealing of buckets and cans; vibration damping; bundling and cable lashing
