Both of BH-2(PMT) and BH-2(PMT)-LS  are made by medical grade modified polyolefin, they are peelable heat shrink tubing and mainly application for aids prodcution for catheters,ballons and guide wires, they need to remove after aids production process or before using. Here is peel off process videos for your kind reference.

The differences in the peel off process:
BH-2(PMT) peelable heat shrink tubing needs heat up (Approx. 85oC) to soften tubing firstly before peel off process.
BH-2(PMT)-LS could be peeled off directly without additional heat and easily after heat shrink process.

Both of BH-2(PMT) and BH-2(PMT)-LS  are made by medical grade modified polyolefin, they have the same performances and applications in the Laser-Welding Application Process Aid for the catheters,ballons and guide wires. Their main applications are as below:
? Processing aid for laser welding of stents andballoons
? Process aid for holding dissimilar materials in hotjaw bonding operations
? Process aid for Reflow sleeve

The differences in the peel off process:
BH-2(PMT) peelable heat shrink tubing needs heat up (Approx. 85oC) to soften tubing firstly before peel off process.
BH-2(PMT)-LS could be peeled off directly without additional heat and easily after heat shrink process.

The diffenrences in the heat shrink temperature:
Both of them have the same fully recovery temperature: +130℃~ +200℃
BH-2(PMT) could withstand Max. shrink temperature 260℃ without bubbles.
BH-2(PMT)-LS could withstand Max. shrink temperature 250℃ without bubbles. 

           

peelable heat shrink tubing

Since medical grade peelable heat shrink tubing BH-2(PMT)  was lanuched into the marketing in the beginning of 2021,our medical peelable heat shrink tubing got a very big  sucessful in the medical industry  and gained the full recognition by the mass customers around the world in past years. Today we proudly announce we  have been developed 2nd generation medical grade heat shrink tubing BH-2(PMT)-LS.

For the 1st generation BH-2(PMT) medical grade peelable heat shrink tubing, its performances are similar as TE-LWA and it needs heat up (Approx. 85oC) to soften tubing firstly before peel off process, the new developed BH-2(PMT)-LS could be peeled off directly and easily after heat shrink process.

In adition, BH-2(PMT) could withstand Max. shrink temperature 270℃ without bubbles and BH-2(PMT)-LS could withstand Max. shrink temperature 250℃ without bubbles.

Different applications require different materials:

• PTFE(fluoropolymer) tubes have a wide operating temperature range (-55 to 175 °C), a low coefficient of friction, and high resistance to chemicals and punctures.
  
• Viton, another fluoropolymer with high chemical resistance, is widely used in hydraulic equipment. It is highly flexible, with a very wide operating temperature range of -55 to 220 °C, making it suitable for protecting sensitive devices against heat.
  
• Polyvinylidene fluoride (PVDF) tubes are intended for high temperature applications.
  
• Fluorinated ethylene propylene (FEP) is a lower-cost alternative to PTFE.
  
• Elastomeric tubes maintain high flexibility even at low temperatures and meet stringent international specifications. Their operating temperature range is -75 to 150°C. The material is resistant to many chemicals (including diesel and petrol) and has good resistance to abrasion, even in severe environmental conditions. A common shrink ratio is 2:1.
  
• Silicone rubber offers excellent resistance to scrape abrasion and high flexibility. Its operating temperature range is -50 to 200°C.
  
• Polyolefin tubes, the most common kind, have maximum continuous-use temperatures from -55 to 135 °C, and are used by the military, aerospace and railway industries. They are flexible and fast-shrinking, and manufactured in a wide range of colors (including clear), which can be used for color-coding wires. With the exception of black, they tend to have lower resistance to ultraviolet light; accordingly, only black is recommended for outdoor applications. A common shrink ratio is 2:1, but high-grade polyolefin heat shrink is also available with a 3:1 ratio.
  
•  EVA:The EVA based formulation with multiple chemicals added to perfect its usage for Electrical applications, has undergone Accelerated Ageing tests. The EVA formulations provide excellent UV and weather resistance to prevent dry banding and erosion.The formulations are Non Halogen and zero Halogen as well.
• PVC tubes are available in several colors and can be used outdoors.
  

Other special materials exist, offering qualities such as resistance to diesel and aviation fuels, and there is also woven fabric, providing increased abrasion resistance in harsh environments.
