The technical principle

The TIZIP MasterSeal 10 is made from high-strength fabric coated with thermoplastic polyurethane. The extra strong plastic teeth are fixed on the top and bottom of the zipper tape. The zipper’s coupling elements keep the sealing edges tightly sealed together when the zipper is closed. The zipper tape can be both welded and glued.

The TIZIP MasterSeal 10 slider is made from a metal compound which is non skin irritating and salt water resistant. The slider movement is contact free and does not wear on the zipper tape or the sealing edge.

Tightness

The TIZIP MasterSeal 10 is easy to operate, and pressure tested to 500 mbar.

Heavy bending may cause leakage. Please try to avoid.

Dirt or Sand

The TIZIP MasterSeal 10 is highly resistant to damage caused by dirt or sand. However if dirt or sand are present, the zipper should be cleaned with soap and water. Dirt particles can affect the sealing function if they get caught between the chain profiles. If the TIZIP MasterSeal 10 closure is used to protect life or sensitive material, the sealing function and cleanliness of the chain area should be thoroughly checked prior to every usage.

Stability

The TIZIP MasterSeal 10’s performance in terms of strength and durability is very good. However, sharp bending or twisting should be avoided.

When closed, the TIZIP MasterSeal 10 has a cross-breaking strength of minimum 125 N/cm.

Reinforcement

For TIZIP MasterSeal 10 zippers, closed both ends and open top, we have a reinforcement for the bottom stop available. We recommend this feature for heavy duty bag applications and for main entry zippers for diving survival and water surface dry suits. The reinforcement strap holds the zipper stringers before they get bent or broken over the edge of the slider in the complete open position.

Operating Force

Opening and closing the TIZIP MasterSeal 10 requires moderate pulling force on the slider. Please allow a slightly higher pulling force to undock the both ends closed version. Some lubrication can help to reduce the pulling force on the docking end. The chain is maintenance free.
