Characteristics 性能特點(diǎn):
With good heat stability and low volatility under high temperature(TGA shown 400℃ for high grade type PETS-4)
PETS在高溫下具有優(yōu)異的熱穩(wěn)定性和低揮發(fā)性(其中高端PETS-4耐溫400℃以上,比硅酮粉潤滑性要優(yōu)異)
1. PETS can be applied as one higher effective lubricant anddispersing agent in plastics and rubber industry in comparsion with PE wax or EBS. (e.g.we recommend PETS-3 to be used in the compounding of PA6,PA66, and PETS-4 to be used in the compounding of PC/ABS,PPO,PPS,PBT,PET,POM,PP,PE,ABS,etc.polymers.),it will mix the main resin with the adding agent more uniformly without defect spot occurred,Besides this,it also show easierdemoulding of the made-up articles from the Molds and improve the plasticization,especially PETS-4(1) is the ideal choice of internal and external lubricant for transparent PC compounding. PETS可作為工程塑料注塑或擠出加工領(lǐng)域中***重要的高溫環(huán)保潤滑劑,相比PE蠟或EBS而言,PETS 具有添加量少、耐高溫性能優(yōu)異、潤滑性突出、不影響透明性等優(yōu)勢,(PETS-3主要應(yīng)用于PA6、PA66尼龍料加工上作為高溫潤滑劑和防玻纖外露劑,PETS-4可用于PC、PC/ABS合金、聚苯氧醚(PPO)、聚苯硫醚(PPS)、熱塑性聚酯(PBT、PET)、PA、POM、PP、PE、ABS作高溫環(huán)保外潤滑劑或內(nèi)脫模劑),此系列潤滑劑添加后可避免出現(xiàn)庛點(diǎn)斑,可使工程塑料樹脂主料與添加劑混合較均勻,除此之外,可使制成品脫模更容易,還可改進(jìn)增塑性。
Dosage 用量:0.1-1phr.
2. It is also one necessary ingredient for compounding Calcium-Zinc heat stabilizers,functioning as the internal and external lubricants,comparing with other same lubricants,havebetter heat stability and low volatility.PETS還可作為內(nèi)外均衡的高溫環(huán)保潤滑劑和輔助熱穩(wěn)定劑用于配制粉體環(huán)保鈣鋅復(fù)合熱穩(wěn)定劑以及粉體稀土復(fù)合熱穩(wěn)定劑體系,與其它潤滑劑相比,具有更好的耐高溫潤滑性和低揮發(fā)性、不析出不影響原有產(chǎn)品的透明性等優(yōu)勢。由于本產(chǎn)品環(huán)保無毒且與PVC相容性極好,還可直接用在105℃級或其它耐熱級別的PVC電纜料中作為高效潤滑劑和輔助熱穩(wěn)定劑,不析出,可顯著提高電纜料的擠出速度和加工品的光亮度。PETS-3側(cè)重內(nèi)滑,PETS-4側(cè)重外滑。
Dosage用量:3-5phr(相對100PHR PVC)。
3. Rubber industry applications,Pentaerythritol tetra stearate is one excellent rubber dispersant and lubricant(similiar to the famous types of Struktol WB222 or Aflux 54) ,can effectively prevent the sticking of the compounds to the rubber rolls,and has positive effect regarding flow and demoulding properties with the injection and mould releasing process,most suitable for synthetic rubber,e.g. H-NBR,ECO/CO,FKM,EPDM,CSM,CR,SBR.PETS可在橡膠行業(yè)用作橡膠助劑預(yù)分散母膠粒料的分散潤滑劑組份,其中PETS-4、PETS-3均有內(nèi)外潤滑的作用,PETS側(cè)重外滑,PETS-3側(cè)重內(nèi)滑,(預(yù)分散母膠粒***主要的分散潤滑劑有PETS、ST,ST會影響硫速,一般不建議使用,但有些地方ST降粘效果明顯,可以考慮,PETS不會影響硫速,且分散潤滑效果明顯)。PETS也可直接適用于CO、ECO和FPM膠種的加工(如模壓、擠出),除降低膠料的粘度和提高對所有品種填料的吸收外,還可顯著減少膠料粘附膠輥的現(xiàn)象;硫化性能不僅不會受到影響,還可促進(jìn)加壓硫化后產(chǎn)品的脫模,減少模垢。作用方式:加入階段:應(yīng)在混煉開始時和填料一起加入。
Dosage用量: 3-5 phr
4. Oilfield industry application,Pentaerythritol tetra stearate also acted as one excellent lubricant applied in the oilfield industry which is biodegradeable,several world famous oilfield service company are now sourcing this solid lubricant for their compounding of oilfield drilling fluids.油田化學(xué)品領(lǐng)域:該產(chǎn)品因在高溫下具有良好的熱穩(wěn)定性和低揮發(fā)性、良好的內(nèi)外潤滑和流動性能、良好的耐老化性、耐抽出性以及電絕緣性和生物降解性,還能在油田鉆井液中作為優(yōu)良的潤滑劑組份進(jìn)行添加。
Note備注:
Pentaerythritol tetra stearate and Pentaerythritol tristearate series have gained REACH pre-registration number and passed SGS inspection concerning SVHC(138 items) and RoHS directives requested by REACH of EU. 耐高溫潤滑劑季戊四醇硬脂酸酯PETS的測試結(jié)果與歐盟RoHS指令2002/95/以及REACH相關(guān)的138項(xiàng)八批高關(guān)注物質(zhì)SVHC要求相符。
