FERMAPOR DD980
The PVC based sealing foam for metal barrel and packaging lids
FERMAPOR DD980 is the brand name for single-component PVC plastisol from Henkel for the production of heat-curing, soft-elastic foam seals.
The FERMAPOR DD980 properties desired by the customers are implemented by Henkel in tailor-made product formulations for different packaging requirements.
The application process
FERMAPOR DD980 systems are processed using single-component dispensing systems usually available on the market. The fluid PVC plastisol is applied into the groove of metal lids for drums or buckets as well as for sealing metal jagged lids through the dosing nozzle of a single-component dispensing system. After a short heat-curing in a specially designed continuous furnace, the plastisol foams up and thickens.
The duration spent in the furnace is usually about 2 to 15 minutes. The oven temperatures range from +170 to +240 °C. The result is a seamless, closed-cell PVC soft foam seal on the metal lid, which can already be installed after a short cooling period.
The foaming process
Material application:
FERMAPOR DD980 PVC plastisol is applied into the lid groove through the dosing nozzle of a single-component dispensing system.
Foaming time in the curing furnace:
FERMAPOR DD980 PVC plastisol foams and sets into a thermoplastic at temperatures from 170 to 240 °C. The duration in the furnace ranges from approx. 2 to 15 minutes, depending on the temperature.
Assembly:
After cooling of the FERMAPOR DD980 soft foam seal, applied in the lid groove, can be used immediately after cooling.
Broad range of properties
FERMAPOR DD980 systems possess a high resistance to many chemicals such as solvents, coolants and cleaning materials, alcohols, hydrochloric and nitric acid, and ammonia gas. In addition, they are characterized by minimal water absorption of < 1 % in an uncompressed condition.
Suitable for the sealing of food packaging
Our phthalate-free FERMAPOR DD980 PVC plastisol is approved for food packaging by EU regulation No. 10/2011. It also meets the requirements of the German LFGB (according to §§ 30 and 31 part 1 of the food and fodder laws), judged by the guidelines laid down by the EFSA (European Food Safety Authority). It can be used in direct contact with liquid, acidic, fat-containing and dry foodstuffs.
