Shanghai Daoqin Plastics Co., Ltd.

polycarbonate (PC) （PC）, by is “ plastics 黄金”, 曾凭借 its excellent property can in engineering plastics light 无限, widely used in electronics electrical appliances, automotive manufacturing, construction building materials and other more field/area. 不, year PC industry, 却仿佛陷入 冰窖, by production capacity and price anionic 霾笼罩, make PC long 期处于黑 dark 时刻. in production capacity 剩, full 球经济 lower 行, lower demand growth slow large lower, PC price lower 行, from 2024 year 14000元/ above, 一路“跌跌不休”, 截至2025 year 7 month 底, already comprehensive 跌破11500元/吨, ultra- 18%. price 雪崩, enterprise profit by pressure shrink, less enterprise 陷入亏 loss 困境.

“ by heavy low transparent polymer/macromolecule material 六边形战士”—— this is for polycarbonate (PC) most 传神, most evaluation.

in industrial and active in, PC材 material tube/pipe 无处不 in, its comprehensive property can 卓越, in more core property can indicators upper performance color, has obvious short sheet/plate, 今天, 我们就 拆 understanding lower PC this 位“六边形战士” 六 large ultra- can force:

1.惊人 impact resistant property （ anti force MAX）

performance : this is PC most is 人知 “绝技”. its impact resistant strong/high degree is 普通玻璃 250倍, is force （PMMA） 30倍 above. use 锤子猛砸一 block PC sheet/plate, it can can lower 一 白点 or bending, 而不会像玻璃 or force that 样碎裂.

principle : PC belongs to 无定形 polymer, separation tool has color tough property and can amount absorption can force.

application : anti elastic 玻璃, safety helmet, anti 护面罩, machine 舷窗, anti 暴玻璃 and other. “打不烂” is it label.

2.极 high transparent degree （通透 property excellent 秀）

performance : light transmittance can 达90% above, and force versus 当, 媲美玻璃.

application : large type light 穹顶, temperature large 棚, high speed 公路隔音屏障, sheet/slice, bottle water and other. it provide 玻璃般 清晰视野, has 玻璃 致命脆 low property.

3. excellent heat stabilized property （ heat resistant property good ）

performance : long use temperature degree can 达-45℃至135℃, short resistant temperature more high. its 玻璃化转变 temperature degree （Tg） in 147℃ left right, high many general purpose plastics （如ABS Tg约105℃）.

application : LED灯 outer housing/shell, automotive lamp covers （ can 承受灯泡 high temperature ）, micro use tool, power tools outer housing/shell, need high temperature medical equipment.

4.良 good machine strong/high degree （ rigid 柔并济）

performance : tool has very high tensile strength, flexural strength and modulus, dimensional stability good, easy deformation.

application : electronics equipment outer housing/shell （如手 machine, 笔记本 electrical 脑）, automotive parts, various gears, bearings and other structural parts.

5.出 color flame retardant property （自 belt/tape “ anti 火甲”）

performance : PC本身 tool has flame retardant property, can UL 94 V-2 grade. through simple modified, can light to V-1甚至V-0 grade （ most high flame retardant rating ）, 且不滴落.

application : electric vehicles battery pack parts, charging stations outer housing/shell, electrical appliances 开关, construction field/area transparent and other for anti requirements high 场景.

6. light and easy processing property （灵 active more 变）

performance : density is 1.2 g/cm³, is 玻璃 一 semi. can through injection molding, extrusion, blow molding and other multiple methods light processing formed complex 形状.

application : from heavy sheet/slice to 几十米 long light sheet/plate, PC都 can 胜任, design degree high.

1.“亚克 force more 透, PC more tough ” 刻 sheet/plate 印象: in very more 人 认知里, force （PMMA） is “ transparent 之王”, property most good. 但实际 upper, high optical grade PC light transmittance filament milli color, and its tough property is force method ratio 拟. PC is “通透且 strong/high tough ”, 而亚克 force is “通透但脆”.

2.“廉价感” 误 understanding : 早期一 low 端PC products （如廉价CD box/case, toys ） can can is processing defect or add material, easy 出现刮痕, 发黄, to lower “不 resistant use, easy aging ” bad 印象. this non PC材 material 本身 原罪, through add resistant UV, hard coating and other modified technology full can solution.

3. light by other engineering plastics cover/cap : in high strength 时, 人们会想 to nylon （PA）; chemical resistance 时, to polyoxymethylene (POM) （POM）. 但PC is that “ full can type 选手”, in need comprehensive property can combined, it is most excellent understanding, very less by 第一 想起.

4.近期PMMA ABS PC market price comparison:

没 has 完美 材 material, PC short sheet/plate main/primary in 于:

• resistant scratch property 差: surface hardness 不如玻璃 and force, easy by 刮花. solutions : surface add hard coating （Hard Coating）处理.

• chemical resistant product property generally : resistant strong/high acid, strong/high alkali, certain has machine solvent agent. solutions : according to use ring selection combined grade or surface 保护.

• long hydrolysis resistant property : in high temperature high wet ring lower, property can can can decline. solutions : use hydrolysis stability grade.

• 应 force cracking toward : for 缺口敏感, in internal stress in lower certain chemical product easy cracking. solutions : optimization product design and injection molding process remove internal stress.

positive is through blending （如PC/ABS alloy ）, copolymer, coating and other modified technology, PC this short sheet/plate by 一一弥补, make its true positive formed is “六边形战士”.

polycarbonate (PC) （PC）绝 non types transparent plastics. it is 集 high transparency, ultra- high toughness, heat resistant, flame retardant, high strength and light 质于一身 engineering plastics 典范. from 守护我们头部 safety 帽, to front 路 车灯; from can machine solid outer housing/shell, to future construction can 穹顶; is in and medical field/area, PC都 in 默默 发挥 不 can substitute/replace function.

it 像一位 low 调 守护者, its comprehensive property can, to 现代生 active 方方面面. therefore, its is “ by heavy low transparent polymer/macromolecule material 六边形战士”, 实至名归! lower 次当您看 to block 看似普通 transparent sheet/plate 材时, 不妨想一想, it very can can is this 位无 不 can “材 material 界六边形战士”—— polycarbonate (PC).
