The pharmaceutical plastic bottle is relatively thin, so the edge of the pharmaceutical plastic bottle should be rounded. Change the details of the pharmaceutical plastic bottle. Increase the circumferential grooves or ribs of the priority of the medicinal plastic bottle, the stiffness and bending resistance of the pharmaceutical plastic bottle.
Longitudinal grooves or reinforced ribs can eliminate the deviation, sagging or deformation of the pharmaceutical plastic bottle under long-term load. Detail shape of pharmaceutical plastic bottle must perform control and use in accordance with the standard form of response, and perform control and use in accordance with the response construction standard. Medicinal plastic bottle common material: Colorants and Processing Auxiliaries Pharmaceutical bottle colorants typically use titanium dioxide TiO2 (anatase type or golden red stone), of which TiO2 content is ≥98% wt, and the amount is 1.0 to 1.5% wt.
Commonly used processing auxiliaries have lubricant stearate and polyethylene wax. All are white powder, add 0.1 to 1% WT. PP material PP is a semi-crystalline material.
It is harder than PE and has a higher melting point. Since the homopolymer type PP temperature is very crisp, many commercial PP materials are joining 1 to 4% ethylene-random copolymers or a higher ratio ethylene content clamp type copolymer. The copolymer type PP material has a lower heat distortion temperature (100 ° C), low transparency, low gloss, low rigidity, but has a stronger impact strength PET material PET is milky white or light yellow highly crystalline polymer, smooth surface smooth and lustrous.
Whent resistance, resistance fatigue, abrasion resistance, well-stability, high wear and high hardness, have a maximum toughness in thermoplastic: electrically insulating performance is good, affected by temperature, but the resistance is poor. Non-toxic, weather resistance, resistance to chemical drugs, low water absorption, weak acid and organic solvent, but no heat-resistant water soaked, non-alkali. The glass transition temperature of the PET resin is high, the crystallization speed is slow, the molding cycle is long, the molding cycle is long, the molded shrinkage is large, the size is very stable, and the molding of crystallization is brittle, and the heat resistance is low.
