Foams, Cork & Rubber
CLOSED CELL FOAM SHEETS
Closed cell foam is defined as a cell totally enclosed by its walls and hence not interconnecting with other cells. Closed cell foam is usually made by subjecting a rubber compound to a gas, such as nitrogen, under high pressure.
We use this time of foam for internal packaging that requires a die cut insert to hold various items in place.
OPEN CELL FOAM SHEETS
Open cell foam is a rubber-like product made by incorporating an inflating agent, such as sodium bicarbonate, into the rubber compound; this agent gives off a gas, which expands the rubber during vulcanization. Foam is usually classified as “open cell” when more than half of its cells are open.
We use this foam for more refined packaging that holds a product in between two layers with no defined product placement.
Cork is an excellent gasket material. Some carburetor float bowl gaskets are made of cork, for example. Cork is also an essential element in the production of badminton shuttlecocks.
We use cork to print calendars on as well the manufacturing of mousepads.
Rubber Sheeting is manufactured from natural and synthetic polymers. Rubber sheeting mostly has a cloth finish on both sides, with a smooth finish in certain polymers.
We usually use rubber to manufacture strips, or mats.
