JINTAI 9900/9900N
ASTM F104:F452111-A9B5E11K6M6
Filled PTFE gasket material
Use:
JINTAI 9900/9900N is widely used in chemical, pulp and paper, food and beverage, and railway tank car industries. This gasket material has been tested evaluated and approved for use in liquid chlorine, caustic soda, liquid oxygen, and high-purity pharmaceutical industries. Among them, 9900N is approved for use in the plasma component manufacturing industry. JINTAI 9900/9900N is designed to be used in situations where it is required to withstand strong chemical corrosion. Unpigmented white gasket materials like style 9900N are available. Both styles 9900 and 9900N (including marked styles) comply with FDA requirements.
JINTAI 9900 is approved for use through the Chlorine Institute's Testing Protocol and is listed as a qualified gasket material for drying chlorine (liquid and gaseous), as published by the Chlorine Institute, Pamphlet No. 95, 3rd Edition. In addition, JINTAI 9900 is approved for use in caustic soda manufacturing equipment. Unlike ordinary glass fiber-filled PTFE gasket materials, the shape of the filler in JINTAI 9900 prevents capillary action that causes corrosion of the flange surface.
JINTAI 9900/9900N has been independently tested and certified (BAM) and is approved for use with media such as liquid oxygen at pressures not higher than 585psi (40bar) and temperatures not higher than 392°F (200°C). Gaskets for oxygen are available from distributor stock, but proper cleaning procedures must be followed before installing such gaskets.
Specifications

Note :
The performance of the ASTM standard is measured based on the base frame plate thickness of 1/16 inches, but ASTM F38 is measured based on the plate thickness of 1/32 inches. These properties can only be used as a general reference and cannot be used as a basis for risk or rejection. The data listed in this table are within the normal range of product performance. These data should not be used to compile technical specifications or used alone as a basis for design.

READ MOREIn the modern industrial field, the selection of sealing materials is directly related to the safe operation of equipment, production efficiency and environmental protection. With the advancement of science and technology and the enhancement of environmental awareness, traditional asbestos-containing sealing gaskets are gradually eliminated due to their potential health hazards and environmental pollution problems, and are replaced by a series of high-performance, environmentally friendly alternatives. Among them, the improved asbestos-free PTFE sheet gasket launched by Jiangsu Jintai Sealing Technology Co., Ltd., has become a leader in the industry with its excellent corrosion resistance, high temperature stability and wide application fields.
improved non asbestos PTFE sheet gasket gaskets are made of advanced filled PTFE (polytetrafluoroethylene) materials. Through special process treatment, they not only retain the excellent chemical stability and low friction coefficient of PTFE itself, but also effectively improve the physical properties and sealing effect of the gasket by adding fillers of specific shapes. The design of these fillers cleverly avoids the capillary action that may be caused by traditional glass fiber filled PTFE gaskets, thereby reducing the risk of corrosion to the flange surface and extending the service life of the equipment.
Chemical Industry: In the chemical industry, facing the challenges of various strong acids, strong alkalis and corrosive media, improved non asbestos PTFE sheet gasket has become an ideal sealing material for corrosive media pipelines and equipment such as liquid chlorine and caustic soda with its excellent corrosion resistance. It has passed the test protocol of the Chlorine Institute and is clearly listed as a qualified gasket material for dry chlorine (liquid and gaseous), further proving its reliability in the chemical industry.
