PLAVIS ® PI (Polyimide) Grades

Plavis®Polyimide Shapes provide superior high temperature resistance, excellent wear and friction properties, good electrical and physical properties and chemical inertness.Plavis exhibits outstanding resistance to creep as well as lubricated or unlubricated performance, ultra-low outgassing, excellent mechanical strength and superior impactresistance. Plavis polyimide is providing application solutions in the industries of aircraft and aerospace, automotive, electrical and electronics, chemical and mechanical engineering,semiconductors and more.

PLAVIS is the Polyimide material offered by Daelim as the most Super Engineering Plastic available in the market.

PLAVIS has a unique chemical structure with some of the highest thermal, physical, electrical and other resistance properties.

Daelim produces PLAVIS raw materials into molded parts, plate/sheet and rod types.

The PLAVIS isostatic rods are known to possess uniformed properties in all directions.

PLAVIS® may be compared favorably to Vespel ® polyimide produced by DuPont.

PLAVIS ® N (comparable to Vespel ® SP-1)

PLAVIS® N is the unfilled base resin grade. Plavis N provides maximum physical strength, elongation, and toughness as well as the best electrical and thermal insulation values. Typical applications include spacers, high-temp fixtures, valve seats, balls, gaskets, insulators, and seals. (see also Duratron D7000 PI)

PLAVIS ® G15  (comparable to Vespel ® SP-21)

PLAVIS® G15 has 15% graphite by weight added to the base resin for increased wear resistance and reduced friction in applications such as bearings, thrust washers, bushings, seal rings, slide blocks and other wear applications. G15 has the highest mechanical properties of the graphite filled grades. (see also Duratron D7015G PI)

PLAVIS ® G40  (comparable to Vespel ® SP-22)

PLAVIS® G40 has 40% graphite by weight for enhanced wear resistance, lower friction, improved dimensional stability (low coefficient of thermal expansion), and stability against oxidation. Typical uses are the same as those for G15.

PLAVIS ® MS (comparable to Vespel ® SP-3)

PLAVIS® MS is 15% moly-filled (molybdenum disulfide solid lubricant) for wear and friction resistance in vacuum and other moisture-free environments where graphite actually becomes abrasive. Typical applications include seals, bushings, bearings, gears, and other wear surfaces in outer space, ultra-high vacuum or dry gas applications.

PLAVIS ® S (Comparable to Vespel ® SPC5000)

PLAVIS-S offers improved thermal properties with continuous use of 350C / 662F,  designed for demanding applications that require thermal and dimensional stability. PLAVIS-S offers higher tensile strength than PLAVIS-N and higher elongation at elevated temperatures.

PLAVIS ® ESD

PLAVIS ESD offers static dissipative properties (surface resistivity 10^6 - 10^9 ohm/square) with high temp resistance and superior mechanical properties.  Ideal for critical applications where static control is required in flat panel display and semiconductor applications.

PLAVIS ® C (Comparable to Vespel ® SP202)

PLAVIS C Polyimide is the conductive grade (surface resistivity <10^3 omh/square) . Plavis C provides excellent physical strength, elongation, and toughness along with being conductive.
