The department is engaged in studying and testing of plastics and polymeric composites and in fluoroplastic technology. It is ranked among the leading institutions developing and processing fluoroplastics in the Czech Republic. metaLOPLAST® self-lubricating bearing foil, the most widespread Czech invention in automotive industry, was developed here. The department has implemented a quality management system according to CSN EN ISO 9001:2008 certified by LL-C (Certification) Czech Republic s.r.o.
Polymers technology:
standardized testing of impact strength and notch toughness Charpy, Izod
creep testing at constant tension stress (23 - 80 °C) and bending stress at three-point arrangement (23 - 60 °C)
light microscopy, density measurement, filler content (pyrolysis analysis), melt flow index, determination of moisture content
determination of hardness using Shore A, Shore D, ball indentation method (ISO 2039-1)
Fluoroplastics technology:
metaLOPLAST® - self-lubricating bearing foil
a foil made of PTFE (Teflon) filled with graphite and glass fibre and reinforced by metallic mesh with low fiction coefficient and high wear resistance
bands with a width of 300 mm and a thickness of 0.48 ± 0.02 mm and 0,78 ± 0,02 mm
SP-25 with tin bronze mesh for loose bearings
SP-25L with tin bronze mesh for bonded bearings with surface prepared for sticking
SP-25N with stainless steel mesh
sliding pads for shifting of bridge structures and dilatation joints with a sliding layer of metaLOPLAST® foil and a pad made of steel and hard rubber
pressed and machined parts made of virgin PTFE and filled PTFE and fluorined copolymers
piston rings, gasket rings and seals made of filled PTFE for compressors and fittings
coatings made of PTFE and modified PTFE mixtures Xylan, for anti-adhesive, sliding and electroinsulation applications up to part dimensions 1 x 0.8 x 0.8 m
coatings of fasteners and metallic parts by Xylan-type fluoropolymers using Dip-Spin Coating technology for the purpose of corrosion-resistant and anti-friction treatment
DELTA-MKS® serial corrosion-protective treatment of fasteners, springs and small metallic parts with coatings of Delta-Tone 9000 and Delta-Seal by Dip-Spin Coating technology (licence Dörken MKS-Systeme GmbH & Co. KG), especially for automotive industry
Delta-Tone 9000 - basecoat on a zinc flake basis with cathodic protection effect
Delta-Seal - topcoat on a basis of curable plastics, possibly with PTFE addition, corrosion resistance during the salt spray test according to DIN 50021 from 480 to 1000 hours; surface treatment of strength bolts and spring elements without a danger of hydrogen embrittlement
new improved materials Delta-Protekt KL100 as basecoat and Delta-Protekt VH 300, possibly VH 301GZ as topcoat
