Avoid Stress Cracks with
Annealing for Solvent Bonding
|
Solvent bonding is a secure and cost-effective solution for assembling plastic components. However, if proper precautions are not followed, the solvents can cause internal stresses to release too quickly and manifest in the form of stress cracking.
Stress cracking is the number one reported failure among solvent bonded assemblies. Stress cracking can occur weeks after assembly, increasing the risk of escaped defect material.
Annealing the components prior to assembly releases these molded-in stresses in a slow, controlled fashion, which improves the parts' ability to resist cracking and increase performance.

Applications of Ultrathin-Wall
PET Heat Shrink Tubing
|
Medical device engineers are always looking for new ways to make devices smaller and thinner, especially catheters, endoscopes, and other devices for minimally invasive procedures. With walls as little as 0.0001" - 0.0005" thick (compared to 0.008" or greater for FEP heat shrink tubing), PET heat shrink tubing is ideal for use in medical devices because it can be left in the finished device without significantly affecting the profile (size). It combines incredible strength and durability with extraordinarily thin walls.
Applications include:
- Braid termination: With high hoop strength, PET can capture a braid and prevent it from rising up.
- Variable-stiffness shafts: Because of its ultrathin walls, PET heat shrink tubing can add stiffness to some or all of a shaft without adding to the profile.
- Electrical insulation: Because of the high dielectric strength of PET, it is ideal for use in energy-generating or sensing devices.
- Pad printing or marking: Our custom configurations allow for pad printing or marking the tubing to avoid printing directly on a device.
