一, core property can 差异

1. heat stabilized property

钙 zinc stabilizer : heat stabilized property relatively low, through optimization zinc ratio/proportion （ usually 1:1至4:1） and add stabilizer （如β-二 ketone , acid ester ） increase property can. long stability property good, combined in low temperature processing （160-200℃）, high temperature lower can can 因“ zinc 烧” phenomenon degradation.

has machine stabilizer : tool has good heat stabilized property, especially combined high temperature processing （200℃ above ）, heat stabilized time long zinc stabilizer. alcohol type has machine 锡（如甲基硫 alcohol 锡） through absorption HCl, unstable chlorine and other mechanism made PVC separation understanding, heat stabilized property excellent other type type.

2. transparent property

钙 zinc stabilizer: transparent property relatively good, 但略逊于 has machine 锡. liquid zinc stabilizer transparent property more excellent, suitable for soft transparent products （如 film, soft tube/pipe ）, can can zinc salt 析出导致 product color dark or light transmittance decline.

has machine stabilizer: transparent property good, suitable for transparent packaging, optical sheet/slice and other for transparent property requirements high field/area.

3. environmental protection property

钙 zinc stabilizer: combined RoHS, REACH and other environmental protection standards, is salt stabilizer substitute/replace product, used for food packaging, medical devices and other field/area.

has machine stabilizer: separation product types （如甲基硫 alcohol 锡） through FDA certification, can used for food contact products, 但含硫 has machine can can 释放刺激 property odor, cost relatively high made its environmental protection advantages application scope.

4. lubricated property

钙 zinc stabilizer: inner lubricated property strong/high, can decrease/reduce outer lubricant use amount, reduce production cost. lubricated property still low separation has machine additives, according to processing demand adjustment formulation.

has machine stabilizer: lubricated property relatively 差, outer add lubricant （如PE wax, oxidation wax ）, can can increase processing complex degree and cost.

5. cost

钙 zinc stabilizer: cost relatively low, property ratio high, combined large production.

has machine stabilizer: cost high, is zinc stabilizer 3-5倍, made its in cost field/area application.

二, application 场景差异

1．钙 zinc stabilizer

suitable field/area:

environmental protection requirements high field/area: food packaging, medical devices, toys, electrical cable and other, meet/satisfy environmental protection standards.

in low temperature processing products: pipe/tube, type 材, sheet/plate 材, tube/pipe and other, processing temperature degree usually in 160-200℃ between.

soft transparent products: 如PVC film , soft tube/pipe and other （需 selection liquid zinc stabilizer increase transparent property ）.

2． has machine stabilizer

suitable field/area:

transparent products: packaging film, optical sheet/slice 材, medical tube/pipe and other, for transparent property requirements high.

processing products: injection molding parts, calendering film and other, processing temperature degree ultra- 200℃.

weather resistance requirements high products: outer 广告布, construction material and other, long UV resistant aging.

三, 选定策略

1. according to environmental protection requirements 选定

若 product meet/satisfy environmental protection standards （如 food contact, toys ）, excellent selection zinc stabilizer.

若 for transparent property requirements high cost can 接受, can selection transparent has machine stabilizer （如甲基硫 alcohol 锡）.

2. according to processing temperature degree 选定

in low temperature processing （160-200℃）: zinc stabilizer property ratio more high.

high temperature processing （200℃ above ）: has machine stabilizer heat stabilized property more excellent.

3. according to products type type 选定

hard products （如 pipe/tube, type 材）: zinc stabilizer can meet/satisfy demand, cost more low.

soft transparent products: liquid zinc stabilizer transparent property has machine 锡, 且无析出风险.

high transparent products: can selection has machine stabilizer, 但需权衡 cost.

4. according to stabilizer demand 选定

钙 zinc stabilizer combined acid ester, β-二 ketone and other stabilizer increase color and lightfast property.

has machine stabilizer usually 无需额 outer add additives, attention/notes and increase agent versus property.
