Velostat vs Linqstat

Velostat alternative LINQSTAT exhibits same chemical susceptibility

Ques­tions regard­ing the chem­i­cal sus­cep­ti­bil­i­ty of the LINQSTAT film have prompt­ed us to answer them pub­licly. On the datasheet of the LINQSTAT VCF-Series Film, the chem­i­cal sus­cep­ti­bil­i­ty of the prod­uct is list­ed. The ques­tions that arose (and the answers below) about the Velo­stat alter­na­tive LINQSTAT are the following:

Questions concerning chemical susceptibility of LINQSTAT

Q1. What does it mean that the LINQSTAT VCF film is unaf­fect­ed by age and humidity?

A1. This means that regard­less of the humid­i­ty (up to 100% RH) and over the entire life of the prod­uct, there is no change in the vol­ume con­duc­tiv­i­ty of the black tape. This is a prop­er­ty of the tape itself. This means that even sub­merged under­wa­ter, the prod­uct main­tains its conductivity.

Q2. What does it mean that there is “slow-attack” from Ketones?

A2. Ketones are chem­i­cal sol­vents, name­ly Ace­tone and MEK. This means that with con­stant con­tact (ie. sub­merged) there is a degra­da­tion of the mate­r­i­al over time. This prod­uct is not suit­able for con­tin­u­ous con­tact with ace­tone (ketones).

Q3. What does it mean that there is a “slow-attack” from Alkalines?

A3. An alka­line is a basic prod­uct (with pH greater than 7) and is the oppo­site of an acid (pH less than 7). A “weak” alka­line means the pH is not very far from 7 (ie. 7.2, 7.4) Stronger basic solu­tions would be high­er than this from 7. With direct con­tact with alka­lines, there is an attack of the plastic.

For many appli­ca­tions, such as the use as an inter­leaver for smart­cards or for the pack­ag­ing of elec­tron­ics goods, nei­ther of these points is an issue.
