Blanson specialise in the manufacture of cast acrylic cylinders, domes, windows and other acrylic products for customer applications that are challenging in terms of requirements for strength, visual clarity, biocompatibility and durability.
When casting acrylic, inclusions in the mix would cause the end product to be compromised so protecting the process from contamination is mission critical.
Unsatisfied with laundered garments
Blanson had not been fully satisfied with the laundered cleanroom garments they used for a number of years. Garments were often returned from processing with contamination still visible and repairs weren’t of a suitable standard. If a garment was pulled out of service for repair there would be no alternative supplied, so if it was from one of the less common size brackets this had a knock on effect with staff sometimes unable to enter the casting room - affecting productivity and profit.
When Blanson had trialled disposable garments in the past, the brand they used would restrict movements and tear, leaving their process exposed to contamination.
DuPont Tyvek limited life garments
An introduction to Cleanroomshop led to a conversation around DuPont Tyvek limited life garments, which after a successful trial, Blanson fully transitioned to in November 2018.
Blanson have found Tyvek limited life garments to be much more flexible and convenient than laundered garments and operatives have been happy with the transition. Even with a wide range of operative sizes there are coveralls that fit everyone and there have been no problems with tears or ill-fitting garments.
The garments are of such good quality that once operatives have worn them in the cleanroom, they can reuse them again in an unclassified area to protect their garments – so they are used to protect process and people.
How did Cleanroomshop help?
Cleanroomshop are helping Blanson to establish an optimum stock level - allowing enough spares to be held in reserve, without holding too much stock. The cost of supply is working out at around the same as with laundered garments, but as the quality is more consistent and operatives are no longer prevented from casting due to lack of garments, it’s more cost efficient that way.
“Cleanroomshop have been fantastic from day one - keeping in contact and explaining everything we need to know - nothing has been too much trouble. We’re now in the process of seeing what other critical goods they can supply,” said Blanson.
Cleanroomshop is the consumables division of Connect 2 Cleanrooms and is a licensed DuPont distributor.
