摘要:
Disclosed is a method for manufacturing a polyester film with low thermal expansion. 95 wt % to 55 wt % of crystalline polyester and 5 wt % to 45 wt % of amorphous polyester are mixed. The blend is then melt extruded to form a sheet. The sheet is then biaxially stretched to obtain a film. The biaxially stretched film is then treated with a heat-setting procedure.
摘要:
An enterosoluble and intestinal-enzyme-biodegradable material is provided. The enterosoluble and intestinal-enzyme-biodegradable material includes a modified amylopectin, wherein at least one of hydrogen atoms is replaced by —CO—(CH2)n—COOH (n is 2-4) and the modified amylopectin has an acid value of 35-180 mg KOH/g. The disclosure also provides a method for preparing an enterosoluble and intestinal-enzyme-biodegradable material.
摘要:
A polyester film is described, including a first polyester and a second polyester. The weight ratio of the first polyester to the second polyester ranges from 1:1 to 1:3. The glass transition temperature of the first polyester is higher than 140° C. and that of the second polyester is lower than 140° C.
摘要:
Thermoplastic vulcanizates are provided. The thermoplastic vulcanizate includes a blend, wherein the blend includes vulcanized acrylic rubber and polyester plastic. The vulcanized acrylic rubber is prepared by reacting an acrylic rubber (ACM) with an epoxy group-containing resin as a vulcanizing agent via dynamic vulcanization.
摘要:
Disclosed are extracts, compositions, and methods for treating cancer and inflammatory disorders. Also disclosed are methods for preparing extracts or compounds for treating the disorders.
摘要:
The synchronous briefing or visual playback in different areas and capability of receiving multiple image sources are achieved by connecting various briefing subsystems in different areas via the Internet. One or more image sources are configured in each briefing subsystem and each connected to a server of the subsystem via physical or wireless network. The server of each briefing subsystem transmits briefing or image data to a playback device for outputting purpose via physical or wireless network. The internet-connected servers in all the briefing subsystems are capable of transmitting briefing or image data to one another via the Internet such that briefing or image outputting in one subsystem can be synchronously performed in other subsystems.
