在西元2000年荷蘭Akzo集團宣布與日本帝人公司達成協議，將Twaron賣給帝人公司，生產廠在荷蘭，年產大約11000噸聚醯胺纖維和紗線。Twaron生產的對位聚醯胺纖維可用於各種市場領域，包括防護服裝、防彈背心和盔甲、輪胎、管件、複合材料、傳送帶、光纖纜繩、傳動帶、墊圈、刹車摩擦片和傳動器飾面。利用TwaronÒ纖維做成的剎車器，其壽命及效果都較石綿(Asbesto)為佳，為少數可用來做為強化的纖維(Reinforcing fiber)，可取代石綿，而提供更好的強度及使用壽命(Durability)。TwaronÒ纖維由於其優良的強度/重量比(Strength to weight ratio)，使得它可用來做為汽車車體，而能在不降低強度的情況下，可大幅降低車體重量。  

    在輪胎方面，TwaronÒ較鋼絲輪圈具有較大的強度和具有吸收能量的特性，且做成之胎唇較鋼絲更具撓曲性，故可改善車輛乘載的舒適性，並可減少噪音及降低在高速行駛輪圈分離的可能性，且可減少轉動的阻力，節省燃料的消耗。應用在自行車方面，車胎方便收納、更換。  

在絕緣－防護市場方面，PPTA單纖維紗、絲狀、以及不織布結構於製造防彈衣和防彈頭盔。其他的保護衣物應用則包括了防切割及耐高溫的手套，以及取代鋼而用於鋼裂鞋尖。非防護性的結構織物則可用於降落傘與帆布。 

Gasoline degradation is an expensive problem for refiners, marketers, customers:

Gasoline degradation is caused by oxidation, polymerization and condensation reactions, resulting in GUMS, high-molecular weight, insoluble compounds. This degradation can occur in all types of gasoline components but likely more in LCC* and HCC** naphthas which make up the bulk of unleaded gasoline; most oxygenates used as octane boosters increase the tendency for degradation. 

To refiners,  

gasoline degradation  means off-specification product and expensive re-running and re-mixing to produce gasoline to specification. 

To marketers,  

gums result in frequent service-calls, front-page news and poor customer acceptance. A lower quality product handicaps distributors in a highly competitive market. 

To car users,  

carburetor or injection needles deposits result in rough idling or stalling, meaning increased fuel consumption and increased exhaust emissions; intake system deposits meaning reduced p ower, impaired drive ability and eventual failure; combustion chamber deposits result in ORI*** increased hydrocarbon emissions and abnormal combustion.

 LCC*     : Light Catalytic Cracked 

HCC**   : Heavy Catalytic Cracked 

ORI***   : Octane Requirement Increase 

Flexsys Santoflex antioxidant protects the quality of your    gasolines:  

Santoflex 44PD is an AMINE-based antioxidant and is very efficient particularly for gasolines with high OLEFINS content.

             Santoflex 44PD offers the advantage to sweeten the sour, corrosive mercaptans by oxidizing them to odorless, harmless disulfides. 

Why are amine-antioxidant preferred rather than a hindered phenol in actual, commercial gasolines? 

 Unleaded gasolines imply the use of alternative octane boosters such as methanol, ethanol, MTBE, TAME, ETBE ...

Catalytic cracked, olefin-rich gasolines in which formation of free radicals and peroxyradicals takes place readily, tend to form degradation products in any way, but in presence of oxygenates this tendency is greatly enhanced requiring compatible antioxidants of a well defined chemical structure such as Santoflex 44PD.

When the olefin content increases, Santoflex 44PD is much more efficient than the classical hindered phenols like BHT.

In the US and in Japan amines are mostly used for gasoline stabilization; in Western Europe amines-use goes hand in hand with catalytical cracked, unleaded gasoline.
