Low Out-Gassing Polyimide Tapes

Low Out-Gassing Polyimide Tape applicationLimiting dangerous out-gassing is critical to manufacturers of specialized electronic devices such as optical devices, hard disk drives, etc. These devices are manufactured or used in high-vacuum environments where even the slightest amount of outgas can be detrimental to their performance. When materials out-gas, they can leave residue on key components that are sensitive to low levels of deposition. This includes even the tapes used to mask or thermally protect sensitive components of a device.

Polyonics XT-620 is a high temperature tape that also meets the low out-gassing requirements of the ASTM E-595 standard. The ASTM E595 test results for the XT-620 resulted in a total mass loss (TML) of 0.81%, collected volatile condensable materials (CVCM) of 0.02% and water vapor release (WVR) of 0.71% when evaluated to 125°C in a vacuum environment for 24 hours.

Polyonics Introduces Engineered Tapes and Label Materials That Protect Static Sensitive Optoelectronic Devices from Harmful ESD Events
Polyonics makes antistatic tapes and label materials with static dissipative surface resistances and low tribocharging pressure sensitive adhesives (PSA) that allow them to protect static sensitive optoelectronic devices such as LEDs, photo and laser diodes, solar cells, etc. and help prevent harmful electrostatic discharge (ESD) events.

Polyonics Announces Expanded Antistatic Tape Product Line:
New Materials, Thinner Constructions, New Coatings and New PSAs Polyonics has recently expanded its antistatic tape and film portfolio to include a wider variety of single and double coated amber and black polyimide and clear and white polyester (PET) constructions. New thinner 40 µm (1.6 mil) antistatic tapes and 13 µm (0.5 mil) antistatic films have also been added for space constrained applications with specially developed matte black coatings available to match specific color and gloss specifications.

Polyonics Introduces High Temperature Bonding Systems for Static Sensitive Devices
Westmoreland, NH (PRWEB) —Polyonics has introduced a series of double-coated tapes that are designed to protect SSD (static sensitive devices). The tapes are well suited for SMT (surface mount technology) applications and provide a strong, thin conformal bond line while generating a very low peel voltage.
