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.

Nordson MEDICAL offers a wide range of precision-engineered polycarbonate stopcocks designed to easily control the flow of a liquid or a gas. Shop online for off-the-shelf components, or contact us to discuss custom assembly solutions.

Looking for a Stress-Free Connection?
Ask our technical experts how annealing and other secondary processes can alleviate the risk of environmental stress cracking in polycarbonate materials.
